Designed in collaboration with Canadian brand Reigning Champ, this adidas PureBoost combines a sock-like textile upper with adidas’ energy returning Boost cushioning technology in the midsole. Tonal laces complement the upper's grey and speckled white look, and the design is finished off with a grey Reigning Champ-branded heel counter. A white Boost midsole and a grey rubber outsole are included underfoot.
