Details In it's fifth iteration, the Challenger furthers its reputation for versatility. Fast and light on the trail, its midsole geometry ensures a smooth ride on the road. While the distinctive multi-lugged outsole leaves you in no doubt as to its trail heritage. Arranged closer together towards the heel for a smoother, more consistent ride, the lugs have a wider spread in the forefoot to help with grip on the trail and in wet conditions. The Hoka One One® Challenger ATR 5 also features a modified midfoot design for improved lockdown as well as a supportive heel counter for lateral and medial security. It looks fast and goes fast.
