Worn once for less than 2 miles, unfortunately they’re a half size too small for me. One look and you'll realize the Endorphin Elite is built to break barriers. Fueled by SPEEDROLL technology, this race shoe features our most aggressive on-your-toes experience. Designed around a slotted carbon plate, it's propulsive and forgiving at the same time. And the ultralight, IAAF-compliant stack of PWRRUN HG foam is the holy grail: delivering ridiculous rebound and cushioned comfort mile after mile efficiency. 4 years in development, Endorphin Elite is the turbocharged marathon shoe you've been waiting for.
