Like that running buddy who never bails, the Challenger 8 GTX 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.
