Stella McCartney's Loop sneakers are a feat of engineering, using an innovative new technique of attaching the upper to the sole without the use of glue. This means that at the end of the sneaker’s life, the upper can be removed from the sole and each part can be recycled. A gradient-effect upper completes the ultra-sustainable design.Made in ItalySole: Rubber 100%Outer: Fabric 100%Lining: Fabric 100%
