Y-3 has a history of creating refined versions of athletic models, and its take on the Ultraboost 21 is no exception. It’s made with a one-piece textile upper and an oversized boost™ midsole that gently cushions and propels each step. There’s a hit of black leather at each heel, too, for a premium finish.
