Extreme comfort gets the boot! The Summit boot joins Terrasoles' popular sherpa collection, made of warm and wooly polyester sherpa and a wool/polyester felt, pieced together with rugged whip stitching. The TPR outsoles are both skid-resistant and eco-friendly, made from partially recycled materials. The removable insoles are designed with arch support, so they are not only good to the earth--they are good to you, too. Care instructions: Keep the Terrasoles Summit clean using gentle machine wash cold, no bleach. Insole should be taken out and hand washed separately. Air dry flat. Looking for other sherpa styles?
