Winter boots made of EVA material with a removable insole. Thanks to the thick, warm insole and EVA (rubber foam with air bubbles) material properties, the boots provide warmth and comfort in air temperatures down to -40C. The boot has a rubber sole that protects it from accidental punctures or cuts. In order to prevent slipping on the ice, a special sight is built into the heel of the boot, which can be used in case of need. The triple, 10 mm thick insert ensures safe thermal insulation: Internal THINSULATE™ insulation layer - provides thermal insulation, as well as absorbs and drains excess moisture to the outside, the perforated foil layer retains the cold, retains body heat and drains excess moisture to the outer layer of the insert. The outer polyester layer provides thermal insulation and wicks away moisture. After use, the boot and liner should be dried separately. Weight is for a pair of boots.
