Made with a sock-like construction, the adidas Originals Yeezy 450 “Stone Grey” features a unique exoskeleton design that adapts to your foot during wear. Breathable Primeknit is used throughout the upper to offer lightweight comfort, plus an integrated rope lacing system helps secure the fit. Underfoot, an EVA foam sole unit extends upwards like a ribcage and is moulded to the silhouette to increase stability and lockdown. This helps reinforce the adidas Originals Yeezy 450 “Stone Grey” where it’s needed most while providing a full range of traction underfoot.
