Topo's slip-on recovery shoe delivers ultimate comfort and relief at every step. Designed to be worn without socks, the repeated ridges of the Ortholite® 3D Wave Sense footbed lightly stimulate and massage the nerves along the bottom of the foot. The Vibram® XS Trek EVO outsole offers phenomenal multi-surface traction and durability for all types of terrain and weather. This shoe feels good and smells good; an antimicrobial blend of wool built into the upper allows the shoe to resist odor while staying warm and comfortable naturally—an excellent approach shoe for a cold day at the Buttermilk Boulders.
