"Like that running buddy who never bails, the Challenger 8 GTX says yes to the road, yes to the trail—and yes to rain, mud and snow. Redesigned with more foam underfoot, an improved fit and reimagined multi-directional lug orientation, it’s both smooth on the pavement and trustworthy on dirt. And its GORE-TEX Invisible Fit waterproof membrane means it doesn’t balk at puddles, either. "
