The Y-3 Ultraboost 5 puts an elevated spin on running shoes. It features a range of subtle yet sophisticated additions to an iconic silhouette, including an all-new TPU heel cage with an embossed Yohji Yamamoto signature and an updated lace cage. An adidas PRIMEKNIT upper, a BOOST midsole and a Continental Rubber outsole give these trainers serious traction and cushioning.
