Like any good sneaker, these RS-X Hard Drive shoes are geared to help you power through each step. Panels of mesh, textile and rubber swish across the upper, offering breathability and soft visual accents. PUMA's Running System tech is practically the nuts and bolts of the engine, supplying comfort and plush cushioning, and the rubber outsole stops you in an instant. There's a plastic heel tab at the back for easy on and off, while subtle PUMA RS-X and Running System callouts sit on the tongue tab, tongue and heel..
