The Andesite Mid Insulated B-DRY Boot is at home in ice-laden mountain towns where snow levels are high and temperatures dip low. PrimaLoft Bio insulation keeps our toes toasty, and a combination of Nubuck leather and textile upper wards off moisture with a waterproof membrane as well. The Vibram sole keeps us firmly planted on the ground, and a lace closure is easy to adjust.
