The 57/40 is dropping along with multiple recent models from the Boston sneakers label. But this one is a spin-off. And of very high quality! For example, this “5740” iteration takes the iconic NB574 silhouette as its inspiration and recharges every feature and material with modern vibes and engineering. The traditional design sees an upgrade with luxe suede, nubuck, synthetic materials, and much more while retaining its vintage aesthetics. The greyscale palette goes sassier when the white N logo and laces appear. Finally, an aggressive and street-ready rubber midsole finishes off the design.
