Product Description These snow boots use water-repellent nylon material and are insulated with Thermolite EcoMade insulation, which is less susceptible to functional degradation when wet. The upper lining features our proprietary waterproof and breathable material, Techproof, combined with a compression-molded EVA midsole to improve the overall waterproofness and lightness of the shoes. A hold system is built in to reduce ankle slippage, and the opening is equipped with an adjuster cord to prevent snow from entering. The outsole uses Vibram Ice Trek rubber, which is suitable for snow and ice.
