Maximum warmth, comfort and support during every winter day. Sidas 3Feet Eco Warm High are the most insulated insoles in the Sidas 3Feet collection, designed for feet with high arches. With an anatomical 3D moulding, they provide precise arch support, stabilise the foot in the boot and prevent excessive pronation under load - ideal for ski boots and other winter footwear.
The EVA foam construction ensures excellent stability, while the heel cup with cushioning helps to precisely seat the heel and absorb shock. The recycled polyester fabric upper and Evamic Insulated foam provide superior thermal protection even in extremely cold conditions. The shape of the liner has been tailored to fit easily into narrow ski boots, without uncomfortable pressure or shifting.
Eco-friendly production from recycled materials reduces the carbon footprint and the Sidas brand contributes €1 from every pair sold to the restoration of forest ecosystems through the Sidas World Foundation.
