Description
With the help of 1.2 million foot scans, we updated Ultraboost with a complete 360-degree female fit upgrade. And we didn't stop there. We redesigned the rubber outsole. We tested hundreds of prototypes. We kept going until we saw a visible improvement in performance. The result? 4% more energy return in the forefoot than the women's Ultraboost 21. The adidas PRIMEKNIT upper includes a narrower heel fit, designed to prevent heel slip and blisters. You'll ride on a BOOST midsole with a linear energy boost system. The shoe's upper is made with yarn containing 50% Parley Ocean Plastic - reimagined plastic waste intercepted on remote islands, beaches, coastal communities and shorelines, preventing it from polluting our ocean.Regular fit
