EVA shells are heat sensitive. They can warp if footwear is subjected to heat. Shoes and boots with EVA shells are light and comfortable, and should be stored properly to preserve their unique characteristics. Do not dry them in direct sunlight or under a hot light source. Do not dry them in the dryer or in front of a window, radiator, hair dryer, or other artificial heat source.
Our high thermal efficiency Primaloft® insulation will win you over with its optimal moisture management and outstanding breathability. Primaloft® insulation wicks moisture outwards, and thus keep your feet warm and dry so you can brave arid winters in comfort!
The EVA Technology
Made of EVA, an antimicrobian material, NAT’S boots are resistant to oil and animal waste. This ultra light self-insulating foam protects against cold and wetness and provides full insulation from the ground. One piece molded, EVA has no seal and, therefore, is 100% waterproof. Filled with thousands of microscopic air bubbles, EVA material is providing high thermal efficiency and excellent cushioning properties.
