4% MORE FOREFOOT ENERGY RETURN COMPARED TO 21鑱絎ITH A COMPLETE 360鎺?FEMALE FIT IMPROVEMENT

With the help of 1.2 million foot scans, we updated with a complete 360鎺?female fit improvement. And we didn't stop there. We re-engineered the rubber outsole. We tested hundreds of prototypes. We kept going until we saw visible improvements in performance. The result? 4% more forefoot energy return, compared to 21 for women. The PRIMEKNIT upper includes a narrower heel fit, designed to avoid heel slip and blisters. You'll be riding on a BOOST midsole with a Linear Energy Push system. The shoe's upper is made with yarn containing 50% Parley Ocean Plastic 閳ユ柡鈧?reimagined plastic waste, intercepted on remote islands, beaches, coastal communities and shorelines, preventing it from polluting our ocean.
