An evolution of the hardcore skate shoe, the adidas Busenitz PureBoost revamps the silhouette with running-inspired updates to the framework. This 'Grey' iteration is constructed with a breathable Primeknit upper, contoured leather heel and elongated tongue. Three-Stripes embroidery and a signature wave pattern offer signature elements. The energized Boost midsole is supported by a grippy rubber outsole cage.
