Up top, the 'Static' 350's Primeknit fabric is adorned with a melange of grey and white hues. This innovative material moulds to the contours of your feet to deliver a supremely comfortable sock-like fit. Another new feature for this colourway: a transparent mesh panel wraps around the sidewall of the shoe, replacing the clean sidewall seen on previous silhouettes. Below, the premium pair utilises adidas' Boost technology. A Boost midsole is made from TPU (thermoplastic polyurethane) which compresses under impact and instantly springs back to its original shape - making for a cushioned ride each and every time. Finally, a gum rubber outsole underfoot blends seamlessly with the pair's Primeknit uppers and provides essential traction to the streets - EF2905, Textile & Synthetic Upper/Synthetic Sole.
