The 3Feet® Eco Warm High insole is designed for skiing, with an anatomical and ecological approach adapted to high arches. Thanks to the 3Feet® concept developed by Sidas, each type of arch has its own level of support. For high arches, this insole incorporates an EVA shell for stability and support, ideal for optimising body alignment. Its recycled polyester felt covering and Evamic insulating foam ensure long-lasting warmth and optimum thermal insulation, while integrating easily into ski boots. In an eco-responsible approach, this insole is manufactured with respect for the environment, with a carbon footprint reduced to around 1.9 kg of CO2. For every insole sold, one euro is donated to the Sidas World Foundation to support the regeneration of ecosystems.
