adidas’s Ultraboost debuted as a runner back in 2015, but as it enters its fourth generation, it’s so much more than that. It’s day-long comfort, thanks to the flexible Primeknit upper and responsive boost™ midsole, and it’s support where you need it most, with its midfoot caging and reinforced heel counter. - Primeknit Uppers - Sock-Like Construction - Torsion System - boost™ Cushioning - Continental™ Rubber Outsole - Style Code: FY9318
