Adidas Terrex Speed Ultra Performance Review

I’ve stuck to running for over five years, and what I benefited from the process is much more than I had expected. For instance, in addition to training my perseverance and stamina, I’ve also learned some knowledge about running shoes and how to choose the most suitable one for myself. This Adidas Terrex Speed Ultra, I should say, is in the list of the most suitable ones and here is its performance review which might do some help for you.

As regards the shoes’ appearance, I have to own that I am quite into it. Its simple but not monotonous black and white with a little pink at the inner side makes the shoes very inviting and unobtrusive. Over and above that, its simplicity makes it very easy to match our daily outfit. After all, not only are the shoes’ performances extremely important, but having eye-pleasing and compelling appearance also matters a great deal.

The Terrex Speed Ultra series is characterized with innovative designs aimed at assisting runners. As for this Terrex Speed Ultra, it is incorporated with innovative technology. For example, the outsole adopts three-dimensional grains, which is inspired by the design of gravel bike, with the purpose of providing convenience to runners. Made of the rubber of Continental, it will offer its owner a better grip than do the majority of shoes in the market right now.

The midsole is made of two unique materials and the height difference between the forefoot and the heel is 8mm, both of which facilitate easy start-up. The Lightstrike cushioning system is a truly excellent one that, combined with boost, provides superior rebound for the heel. During my running, the feedback under my feet seemed endless and I also seemed to be supported by the ceaseless “energy” underfoot.

The shoelace system is designed in a novel way so that the tongue is firmly fixed instead of sliding to the side, which, I think, is set to solve the problem that many people are troubled by. If you take a closer look at the tongue, you can find many holes in it that enhance the heat dissipation and prevent your feet from being bound by sweltering running shoes.

Over and above the aforementioned, there is a detail that should be made particular mention of. That is the number of holes on each of the three bars is different, showing the ingenuity of the shoe’s designer. And the laces are flat ones, which increases friction and prevents themselves from loosening during running.

Take my personal experience. One day last weekend I did a 15km workout, at the end of which I was tired, but I was still rather motivated and at ease, which I think should be credited to the lightness of the shoes.


To sum up, the TERREX SPEED ULTRA is a well-designed, lightweight as well as well-constructed off-road shoe designed for improving and increasing comfortness. However, it’s fair to say that this isn’t a versatile off-road shoe and is not suitable for everyone. Despite that, if you are searching for a lightweight and fast running shoe that is designed for long distances and can provide plenty of cushion on tough, rugged roads, then Adidas TERREX SPEED ULTRA would be a great choice.

Adidas TERREX AGRAVIC ULTRA Performance Review

For a runner to do his level best during cross-country races, a pair of good cross-country shoes is essential. In my case, I will choose shoes according to the different road conditions; after all, the more you know about the “enemies”, the likelier you will win. Anyway, here I wanna recommend this Adidas TERREX AGRAVIC ULTRA which can save you much time in choosing shoes because it is both suitable and reliable for various kinds of roads.

My first impression of the shoes was that it looked simple yet quite inviting. It just turned out that the shoes can be matched with all manner of everyday clothes. With respect to the vamp, Adidas adopts some breathable material to improve comfortness. The mesh of the vamp is relatively hard though, it is easy to wash and quite durable. Besides that, the toe, as is shown in the picture, is designed in such a way that the protection there is splendid, which many brands have failed to do.

The upper is made of relatively hard material that is aimed at protecting the wearer’s ankles while offering support at the meantime. For the weight, a single shoe weighs 295 grams, which is at the average level.

In terms of the outsole, it is not widened because widening will only make the shoes bulky. During my matches and training, I can definitely feel the agility of the shoes. With the grains and materials of the outsole, I am further assured of its grip and durability.

Last week I put the shoes to a long-distance test. After the first test of around 15km, I didn’t feel any discomfort. When I was going downhill on gravel and dirt roads the shoes could provide me with good skid resistance. It was not that challenging for me to run uphill for it also offered perfect support for me even as I landed my forefeet first. In a nutshell, it can offer me excellent support on the uphill, and even after the downhill and the smooth flat road, I feel no aches or pains from the lactic acid buildup.

When the second 15km test was finished, I was somewhat taken aback by the cushion and feedback provided by the midsole. I felt like the shoes were my old friend for many years because they know me very well. The rear part of the sole is prominent in preventing slipping, and both the front and middle part of the outsole ensure cushioning and support that are badly needed for different road conditions, which sounds terrific and intelligent.

As time passed by, I felt a noticeable fatigue during the next 30 to 60km test. In the more rugged sections, the disadvantage of the hard upper is obviously felt. When I turned left or right downhill, the hard upper would produce pressure on my ankles, which requires some protection there rather than just wearing a pair of thin socks. To my relief, when the test was over, there was hardly any wear in the outsole.


In short, this Adidas TERREX AGRAVIC ULTRA is certainly not perfect. Not only does it have advantages, but also shortcomings that cannot be ignored. Notwithstanding that, the advantages still outweigh the disadvantages, and the shoes are therefore generally satisfactory. But anyway, before purchasing, you’d better have a try in the flesh so that you may know whether it is suitable for you. After all, you won’t know if your shoes fit until you put them on.

Skechers Speed Freek Performance Review

As a running lover, I was not endowed with much gift and I therefore make up for this with my passion and efforts. During the past seven years I’ve racked up over 15,000 miles of running, which to me was more than a reward, but more of a motivation. I enjoyed my running process very much, which should, to a certain extent, be attributed to my shoes despite that some of them are barely satisfactory. Here I wanna recommend Skechers Speed Freek which should be at the top of my 20 running shoes regarding their overall performances.

As soon as I got the shoes, I was informed from the shoe box the technologies adopted. First of all, there is the CARBON INUFSED in the forefoot. Secondly, the outsole is made of rubber of GOODYEAR. Over and above that, the midsole is hyperburst, much thicker than that of its predecessors. Finally, there is also the HYPER ARC that helps speeding up.


As regards its appearance, there is a combination of white, gray, black and bright red as that of a watermelon. Nevertheless, it is not so much the shoe’s appearance as its performance that impresses me deeply.

The big hollow logo “S” is printed on the outside of the heel, but it is not in the least eye-catching. At the height of highlighting one’s own brand by emphasizing its logo, Skechers, however, chooses a different but not showy way.

The midsole adopts the multi-layer structure with black on the upper and white on the lower, which is thickened to provide better cushioning and rebound. As for the vamp, it is made of mono, a kind of gauze widely enjoyed, to improve the shoes’ breathability and reduce their weight. Besides, seeing that there are people who stick to running on wet roads, the shoes’ vamp is made waterproof to provide them a better experience. This, by some estimate, has helped increase consumers by 5%.

The tongue of the shoe is perforated to improve the air permeability, with a V-shaped slit at the top and “Speed Freek” printed on it.

Hyperbust is Skechers’ strongest technology and has been used in skechers’ running shoes for a couple of years. But the midsole of this Speed Freek has been thickened with the fore part 32 mm thick and the heel 36 mm thick. Actually, the thickening of midsole is in great popularity in recent years and Speed Freek is just following suit. However, in spite of that, I must own that Speed Freek has done a better job. Thick as the midsole is, it is still superior in offering rebound.

The insoles are inseparable from the shoes for they are firmly attached to the midsoles so as to avoid its being pushed out during running.

However, the shoes are not without shortcomings. The heel is in fact very soft since it is not equipped with counter. From the perspective of my experience, this is the most glaring disadvantage of the shoes because it has gone so far as to reduce their weight by eliminating the counter.

The orange part of the outsole is covered with Goodyear wear adhesive, which, however, doesn’t seem to help improve durability of the outsole. I had even thought that it might only accompany me for 1000km.

The two hollows in the arch, the so-called HYPERARC, in addition to further reducing the weight of the shoe, can also help speed up runner’s pace.

With the above efforts, you may be wondering how much these shoes really weigh. Actually, a single Speed Freek I got here weighs only 202 grams while a shoe of other brands mostly weighs above 220 grams, from which we can get a glimpse of the excellence of the shoes.


With this pair of running shoes, I am even more enthusiastic about running. After running ten kilometers for three days in a row last week, I didn’t feel any discomfort under my feet at all. To sum up, there do exist some disadvantages of the Speed Freek, it is overall terrific and a good choice for the majority of people.

Curry Flow 9 Performance Review

For the Curry fans, he is the center of attention on the court and his performance tugs at millions of heartstrings. Outside the court, his basketball shoes are also widely enjoyed and attract the attention of many fans. Finally, he was in the media spotlight wearing his sneakers, so here we have the clearest picture of Curry Flow 9 ever.

It has always been said that what UA has been doing in recent years is helping its athletes improve their athletic performance on the court, and Curry Flow 9 is again living proof of this.

This Curry Flow 9 is a co-branded series with Sesame Street, but some reviewers said that there seemed no big difference between Curry 9 and its predecessor. If anything, it has become uglier. However, from the perspective of performance, being lighter, stronger and more durable is the most glaring improvement of Curry Flow 9.

The two colorways of Curry 9 are cartoonish, not least the yellow and pink one that looks quite like “a sweet strawberry ice cream”, as is called by some fans. In terms of the shoe’s weight, it has been made much lighter. For example, the Curry Flow 8 weighs 340 grams, which has been quite a tremendous job of UA. However, when I got Curry 9 in my hand, I was again astonished by its lightness.

Curry 9 is equipped with UA Wrap technology, which has been used in the previous Flow Velociti Wind. After adjustment, the vamp is more supportive and endowed with more excellent wrapping performance. Meanwhile, the vamp, after improvement, can be better attached to the wearer’s feet. Aside from that, the different colored lines on the vamp, as can be obviously seen, are like miniature safety belts, helping fix our feet inside the shoes.

Over and above that, the shoe tongue is different from the previous one. The integral tongue of Curry 8 is now converted into a traditional separated one in Curry 9, which is easy for adjustment so that even people with high instep will find the shoes agreeable.

The midsole is the Flow tech that has been seen in Curry 8. Although the tech has a good reputation, it is not without disadvantage. That is the tech is not durable enough so as to offer its owner a long-lasting experience. In the previous work, the outsole is eliminated to reduce the shoes’ weight. Similar trace can also be found in Curry 9 because the shoes, after all, are tailored to Curry. Although the shoes might not be suitable for the majority of people, I do believe that the shoes will still be the best choice for many fans.

With respect to the grip, just take my personal experience. Last week when I was playing basketball on clean wooden floor, the shoes were always offering me quiet yet outstanding grip. Therefore, I am rather satisfied with its grip. But if you are accustomed to outdoor courts, you’d better take care of the soles before and after your playing.

The midsole TPU has also been changed beyond all recognition. There are now two small visible TPU, which further reduces the overall weight of the shoes. The upturn of the toe is much more conspicuous, and the widening of the sole and the grains both inside and outside indicate that the shoes are positioned entirely for players like Curry.

For the cushioning, one friend of mine highly thought of it the other day when we were playing basketball. However, from my perspective, I don’t think there is much improvement if compared with Curry 8. As a matter of fact, I’d rather the Flow material can be changed to a more durable one. After all, my Curry 8 has accompanied me for only 10 months.

The inside of the heel is not overstuffed, but there is a very obvious concave and the counter is placed in a very high position. Yet I don’t think this a great bother.


In a nutshell, this Curry 9 is an excellent sneaker. It seems like an upgraded version of Curry 8, with its vamp strengthened and its support, protection, wrapping and grip greatly improved, making itself more suitable for more people. It is most likely that we’ll see Curry repeat his feat this season, and Curry 9 will then be endowed with new meaning and values.

Unboxing and Closed Look: Jordan Why Not.5

When I first saw the pictures of Jordan Why Not.5 on the Internet, I was taken aback at it because it looked as if it were my old companion. Previously its leaked photos have also attracted great attention of many sneaker fans. Now that the pictures of the shoes have been released by the official, it is essential to get some knowledge of the shoes before deciding whether to buy it.

There are four colorways of the shoes, all of which, on a personal note, are very showy. But on the other hand, this is one of the aspects that distinguish the Jordan Why Not shoes from others.

The brand-new Jordan Why Not Zer0.5 applies a variety of materials such as organdy and suede to the upper, ensuring breathability while at the meantime enhancing durability.

Although I myself have several pairs of the Jordan Why Not shoes, I was, like many fans, shocked by the bombastic overall appearance of Jordan Why Not.5. There in the shoes are quite a few jagged, asymmetrical designs, which alone are able to make the shoes stand out.

Over and above that, the shoelace system is reinforced with straps, heel TPU, etc., so as to ensure that the foot is firmly attached to the shoes during movement, thus providing professional protection and stability.

The Zoom Air cushion on the front part of the midsole ensures excellent cushioning performance whenever there are breakthroughs, emergency stops or shooting.

According to the official news, each of the four colorways will be released successively between February and April at a price of $150, which is set to excite many fans once again.


These four colorways are all eye-catching and recognizable. Apart from their appearances, the upgraded setups in the shoes will also stand the shoe owner in good stead, and might even help reverse the final outcome. This, I think, should be a temptation that is hard to resist.

Unboxing: KYRIE 8

Just as Irving’s performance on the court has received a lot of attention, so has the series of basketball shoes. In fact, because of the KYRIE shoes’ excellent performance, they have always been widely enjoyed. Therefore, when this KYRIE 8 was launched, many people doubted whether it could be as satisfactory as its predecessors. Anyway, to get some knowledge of the shoes, it’s a must to take a close look at it first.

There have been several colorways of the shoes. Each of them has its own features and can therefore cater to the needs of different people.

For the colorway below, the vamp is a large tiger pattern comprised of purple, black and light green. In the tongue of each shoe, there are printed with different logos. Besides, the shoelace system is designed in such a particular way that it can improves the shoes’ overall wrapping performance.

It can be obviously seen from the side that the tongue is designed very high and the padding in it is very thick. However, whether such thick padding can enhance wrapping still remains to be tested.

The material of the upper is different from that of the front part. There is a large area of leather and quite a lot of padding.

The previous Kyrie shoes are equipped with only one Zoom, but now we can find two Zooms in KYRIE 8, which is actually a great improvement. However, the Zoom at the heel is so small that its performance might be barely noticeable.

The design at the heel is all the more elegant and simple. A logo of “Irving” is eye-catching there, but it is nothing more than a decoration. In short, I don’t think the heel design is outstanding or deserves much attention.

My first impression of its outsole was that it was so large and flat, and I even doubted whether the shoe could provide me with the grip I had expected of it. For all that, I must confess that the grains in the forefoot are very nice and distinctive. In the middle of the sole there is also a signature of Irving and the back part is marked red with the number 8, which is highly practical.


To sum up, this KYRIE 8 may not be superior to KYRIE 7 in its appearance, but its setups are certainly improved. Although Irving himself is not engaged in the design of the shoes, that’s not to say that there is nothing to recommend them. But anyway, ultimately it is you who are in charge.

CURRY 9 Performance Review

Probably because of the historic moment when Curry was crowned the “NBA’s 3-point champion” and the great success of Curry 8, this Curry 9 has been the source of heated discussion before it was officially launched. As of today, it has been some time since the shoe’s official release, but it still enjoys great popularity in this circle. Regrading its overall performance which, I think, is what most people are concerned about, the performance review of Curry 9 is necessary and here it is.

The first glance of the shoes has made me obsessed with it. Its various colorways are quite refreshing and finally I picked this pink and yellow one out of personal preference. Some says that this colorway is not only childlike, but also perfectly matches Curry’s adorable image. I think he has revealed the essence and character of the shoes.

Comparing Curry 9 to Curry 8, I found that the integral design of the tongue of Curry 8 has been changed to a more conventional separated one, which makes the shoes become suitable for a wider range of people and improves flexibility at the meantime.

Aside from the colorways, the most obvious upgrade to the Curry Flow 9 is its vamp. It adopts the Warp, a tech once used in Flow Velociti Wind, whose multi-layer woven structure can firmly fix the wearer’s feet in the shoes. Besides, the tech is also extremely breathable, and during nearly two hours of combat yesterday, I didn’t feel sweltering in my feet.

If you have also a pair of Curry 8, you must have an intimate knowledge of its lightness. However, it is still beyond my imagination that Curry 9 is made more lightweight. A single Curry 9 of size 42 weighs about 300 grams, which is actually second to none at the moment. And thanks to its brilliant wrapping, you can expect a pleasing wearing experience.

Compared with the upgrade of the vamp, the improvement in the midsole stability is not that conspicuous. The special treatment of the additional TPU in the arch is impeccable in both its area and the excellent midsole rigidity in actual combat. Such design is just right with the enlarged outsole of the forefoot, which ensures excellent stability without losing ankle flexibility.

The excellent of the Flow tech has already been proved by many sneakers, not least by Curry 8. Despite that, however, you’d better wipe the soles clean before playing so as to put your capacity to good use. As a matter of fact, it is a shoe’s wrapping and grip that are the core need for a player when it comes to high intensity exercises. Therefore, for many players, this Curry 9 will be a best choice for the shoes are endowed with both excellent wrapping and nearly perfect grip.

Nevertheless, the shoes are not without disadvantages. The fly in the ointment is that the wear resistance of Flow outsole is relatively poor, so the shoes is more suitable for playing in the indoor wooden floors or rubber fields. For those who are accustomed to the asphalt fields, I think the shoes might not perform as well as it is expected.

Many reviewers have said that they are also attracted by Curry 9’s cushion so that the shoes have become also a daily necessity for them. In my case, whether I am to make breakthroughs or to start up, Flow always provides instant feedback for me.


If you’re the one who are in need of extreme flexibility and lightness, and are good at shooting, Curry Flow 9 is your best choice. Like Curry’s magic “3-point”,  the shoe is in a sense a magic as well and may even help reverse the outcome of a match, which, I think, is beckoning and hard to refuse.

LEBRON 19 Performance Review

From the intense publicity at the beginning to the recent release, the LEBRON 19 have earned quite a lot of attention. With great expectation I bought this LEBRON 19 which is also the fifth LEBRON shoes I’ve ever had. Since you are concerned about the details of the shoes, let’s take a closer look at it.

With regard to a shoe’s appearance, “There is a thousand Hamlet in the eyes of a thousand readers.” From my perspective, I am very delighted to have found a pair of shoes that go well with my daily dressings.

A single shoe of size 42.5 weighs up to 548 grams whereas a pair of size 43 ZK8 weighs no more than 540g. Therefore, from its bulky appearance we can also get a glimpse that the shoes won’t be lightweight. However, I think it is understandable because lightweight shoes aren’t necessarily the best choice for a player like James.

The midsole is equipped with a Zoom in the forefoot as well as an Air Max in the rear part, which at the first glance is similar to Vapormax 2.0. However, it is a pity that the air cushion in the forefoot is not installed with any reinforcement so that the outer sole deforms easily.

As for the cushion in the heel, it also deforms easily even if it is pressed simply by hand. Compared to the LBJ18’s Max270 air cushion on the rear part, the cushion of LBJ19 is much softer. Therefore, I think the setup has gone over the top and is not so suitable for a wide range of people. In other words, only a few people may be able to harness it.

Although the cushion looks nice and compelling, it is doomed to be a failure because it can’t ensure excellent stability, either.

Different from both LBJ17 and LBJ18 whose vamps are large area of Knitposite woven ones,  LBJ19 is equipped with a meshlike translucent vamp, which is relatively thin but the rigidity of which is not strong enough to offer sufficient support. Both sides of the upper are filled with two air bags around the ankle, and there is a low-top design in the inner part that is similar to that of CJ1, which indirectly improves flexibility.

Above the shoe tongue, there is also a small air bag, further enhancing the shoe’s overall wrapping. The shoe’s wrapping performance is not that terrific though, it is still sufficient and helpful to a certain extent.

As of today, I’ve wore the shoes for 20 matches, but each time its grip performance turned out to be barely satisfactory. Taking a look at its outsole, it seems to be made of lots of little bricks and its grip should be as good as it looks. However, in the wood floor test, the LBJ19’s grip performance was very mediocre. Whenever I Whenever I make an emergency stop, there will be a certain degree of deformation in the sole. And when it is compared with other shoes, say, KT7 and AG2, its grip is all the more disappointing.

Anyway, I must admit that this  LBJ19 has been improved by leaps and bounds relative to its predecessors. As for whether the shoes can gain your favor completely depends on you. After all, everyone’s physical conditions are different.


To sum up, this LEBRON 19 does contain a lot of Nike’s efforts and can be a symbol of James. Although there is still room for improvement, the shoes are actually very nice. For heavier players like James, the LEBRON 19 is more than suitable and can be a very excellent companion. But for those who weigh less, the shoes might not be the best choice.

Unboxing: Jordan Why Not.5

Previously I had a splendid impression of Jordan Why Not.4, and with great expectation I bought this Jordan Why Not.5, hoping that this new sneaker would still be my able helper on court. Here is the brief introduction of the shoes’ setups.

Regarding a shoe’s appearance, it has always been a matter of opinion. Therefore, here I don’t want to express too much personal opinions about the appearance of this Why Not.5.

Compared with Why Not.4, this Why Not.5 is lighter, weighing about 410 grams. The shoelace system also helps make the shoes stand out because of its convenience. Besides, the design of the shoelace system further enhances the shoe’s wrapping performance. When I first wore the shoes, I felt as if I were wearing a pair of particular tight socks that fit tightly to my feet.

The material of its vamp is the sort of lightweight one commonly used in running shoes, which partly accounts for the shoe’s lightness. Actually, the material feels very comfortable and is also friendly to our skin. As is shown in the picture, there are quite a few air holes in the vamp, thus ensuring superb breathability.

In the arch there is the TPU for offering support and anti-torsion, which is common to all the Why Not shoes. The grains of the outsole and the cushion setups of the midsole are both upgraded. In terms of the outsole, it is made of relatively hard rubber, XDR, which, according Nike, can be relatively durable. But with respect to its grip performance, I don’t want to rush to a conclusion for the shoes need some more testing. As for the cushions, the front parts of the soles are installed with a large ZOOM AIR so that the wearer can feel terrific feedback on the forefoot.


In a word, Jordan Why Not.5 does have some excellent tech while its overall performance requires some more testing. If you are now considering buying this Jordan Why Not.5, just stay tuned for more performance reviews about it.

Kyrie Infinity Performance Review

This Kyrie Infinity, so called Kyrie 8, has failed quite a few reviewers. Anyway, for those who may be considering buying this Kyrie Infinity, an objective review of the shoes is necessary and here it is.

The first impression it gave me when I held it in my hands was that its materials felt very bad and its workmanship was also mediocre. In order to make up for this, Nike adopts genuine leather from the edge of the forefoot to the upper. Compared with its predecessors, however, this Kyrie Infinity is still far from being satisfying.

Nike’s last is still there and is also superior in quality. With this, I can enjoy excellent comfortness offered by the shoes. Besides that, I found that so long as I fasten the shoelaces, the shoes can still provided me with good wrapping. But it should be made particular mention of that the wrapping in the front part remains to be improved because of the thin materials used there.


Both the inner part of the heel and the shoe tongue are padded with a lot of foam, which, as is known to many sneaker fans, won’t lead to the desired result. “The more, the better.” doesn’t apply here. Therefore, if you are in need of particular excellent wrapping, you are very likely to get disappointed at this Kyrie Infinity. But on the other hand, one of its advantages is that it can be suitable for a wide range of people with different foot shape.

In the forefoot a Zoom Strobel is used which is the same as that in GT Run, but I don’t think it has done a better job than Zoom Turbo. In the heel, there is also a Zoom, but you can barely feel it if you don’t take a closer look at it. In spite of that, “half a loaf is better than no bread.”, and it is certainly stiffer than foams, offering a relatively nice support.

I have to admit that it was beyond my wildest dreams when I found that Nike equips the shoes with an anti-torsional device in the arch. However, it just turned out that the device’s role is minimal:it is not hard enough so that it can’t offer any support in the midsole. And with the soft vamp material, the shoe’s anti-torsion performance has gone from bad to worse. Therefore, you’d better not expect too much of it. After several rounds of matches, my feet has suffered a lot.

Taking a look at its outsole, I had thought the shoe’s grip would be satisfying. However, it failed me once again. The rubber of the outsole is again rather soft and is therefore prone to deformation. When I was playing basketball yesterday, I almost slipped a couple of times, from which you can see its poor grip performance.

For its cushioning performance, you can’t expect too much of it, either. Owing to the position of the cushion in the forefoot, I didn’t get much benefit from it.

However, this Kyrie Infinity is not without advantages. A single shoe weighs about 400 grams, which is above the average level. Over and above that, its breathability, I think, can be listed as superior. Personally, I get sweaty easily on my feet, but I don’t feel stuffy in the shoes.


To sums up, this is the worst Kyrie shoes of the series. To a professional player, this Kyrie Infinity is definitely unsuitable and not qualified for high-tensity way of playing. But for daily low-intensity exercise, these shoes are more than sufficient.
