Released as part of the adidas Parallel Dimension collection, the Crazy 1 ADV 'Grey' is one of many colorways that take classic models and makes them futuristic. The sneaker features a mesh and suede-based upper with breathable panels on the forefoot. The sneaker also sports additional suede accents on the eyestay, toebox, and heel, an elasticated tongue for an adaptive fit, and a cushioning midsole for comfort.
