If going fast on trails is second nature, the easy-fitting Chameleon II Stretch is second skin. Built with more reinforcement material along the upper than most trail running shoes, Merrells easy-access trail shoe features extra comfort and fit features like an elastic cord lacing system and convenient friction cordlock. Above the impact-absorbing Air Cushion midsole is a contoured 4.5-mm. anatomical footbed backed by a supportive nylon 6.6 injection molded arch shank. The Vibram Chameleon Sport sole looks narrower than some bulky hiking shoes, but Merrell divided the high traction sole between long-lasting Dura rubber lugs and grippy Versa rubber lugs for reliable hold on a range of surfaces. If youre looking for some extra weather protection, consider checking out the waterproof and breathable Merrell Chameleon II GORE-TEX XCR shoe.
