Hoka Men's Challenger 8 GTXRain or shine. Street to summit. Like that running buddy who never bails, the Challenger 8 GORE TEX says yes to the road, yes to the trailand yes to rain, mud and snow. Redesigned with more foam underfoot, an improved fit and reimagined multi directional lug orientation, its both smooth on the pavement and trustworthy on dirt. And its GORE TEX Invisible Fit waterproof membrane means it doesnt balk at puddles either. Guess youre out of excuses.
