The all-terrain HOKA Challenger 7 gives you road performance with trail traction, so you can run wherever life takes you. HOKA improved the Challenger by re-engineering the 4 mm lug pattern to provide a smoother road running experience while still giving you great grip for trail runs. The durabrasion rubber outsole extends the longevity of the shoe no matter what surface you run on. Designers also added more cushioning in the midsole to increase the stack height and allow you to run comfortably for longer. A brand-new upper provides plenty of breathability as you put in the miles. New engineered mesh fits better around your feet and is made with recycled material. esters noticed that this shoe was not as narrow as the previous version in our HOKA Challenger 7 review. Plus, there is an extended heel pull for easy entry if you are changing shoes during an ultra marathon, or trying to quickly put your shoes on as you dash out the door for your run. Whether you are hitting the roads, trails or both, do it in comfort with the HOKA Challenger 7.
