No limits- admirable mantra, but easier said than done. The Grand Traverse is our best effort at making it happen. Start up a rocky, loose hike and the dual-density EVA footbed and molded EVA midsole happily oblige. Change plans to an exposed ridge traverse, and fear not- the Vibram Ibex sole features dual-compound rubber to maintain grip under your toes, but wet-weather traction underfoot and beneath the heel. Climb, descend, hike, repeat- that's a Grand Traverse.
