Sidas 3Feet ECO Warm Mid Arch Insoles

The 3Feet® Eco Warm Mid insole delivers specialized support for medium-arch skiers seeking comfort and performance on the slopes. Built on Sidas' proven 3Feet® concept, this insole features a structured EVA shell that provides targeted stability and support, promoting proper body alignment and reducing fatigue during long days on snow. Engineered with sustainability in mind, the insole combines recycled polyester felt with Evamic insulating foam to trap warmth and maintain thermal comfort in cold conditions. The low-profile design fits seamlessly into ski boots without bulk, making it an ideal upgrade for skiers looking to enhance both support and warmth without compromising boot fit.
