Product Detail: adidas Originals low profile shoes inspired by the '90s equipment series feature a scaled back design and mix modern materials with retro style with a knit upper and moulded EQT detailing. BY9511 Breathable textile and synthetic upper. Textile lining. Sock-like Flyknit upper contours to your foot for lightweight support. Burrito tongue. TPU cage overlay for stability and support. Boost™ energy-returning properties for endless supply of light, fast energy. STRETCHWEB rubber outsole is lightweight and elastic, adapting to the ground for stability and working strategically to optimise the unique properties of boost™ from touchdown to push-off. These have been worn so are preloved but I would say maximum 3 times as spotless throughout without any real wear on the outsole.
