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 Merrell's 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 and a female-specific Q-Form™ triple density compression molded EVA frame. 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 you're looking for some extra weather protection consider checking out the waterproof and breathable Merrell Chameleon II Gore-Tex® XCR® shoe.
