A game-changer on running tracks that was embraced on the streets, the adidas Ultraboost redefined comfort with their Primeknit upper and Boost midsole cushioning. The original model returns with the adidas Ultraboost 1.0. The sock-like knit upper gets the trusted support and style of the midfoot cage and Fitcounter heel. Visible Boost technology delivers plush cushioning and all-day energy return while the Stretchweb outsole delivers that trusted grip on the streets.
