Using over 1 million foot scans, we've updated the Ultraboost with a 360-degree optimized fit for women. But we didn't stop there. We've also redesigned the rubber outsole. We tested hundreds of prototypes. We persisted until we saw clear improvements in performance. The result? 4% more energy return than Ultraboost 21 for women. The adidas PRIMEKNIT upper has a narrower fit around the heel designed to avoid blisters. You get to fly on a BOOST midsole with a Linear Energy Push system. The shoe's upper is made with yarn that contains 50% Parley Ocean Plastic, which is recycled plastic waste collected from islands, beaches and coastal areas, so it doesn't pollute our oceans.
