About
3Feet® Eco Winter High
Sidas 3Feet® Eco Winter High: pre-moulded ski-boot insole for high arches. Sidas's 3Feet® concept comes in three arch heights (High, Mid and Low) so the support matches your foot type.
The EVA shell gives stability and foot support. A thin woven polyester mesh top layer paired with Evamic Insulated foam provides thermal insulation against the cold, and the insole is shaped to fit easily inside a ski boot. Eco-designed: Sidas favours low-impact materials such as plant-based or recycled materials.
Construction
- Top cover — 100% recycled polyester (PES), woven pattern to keep warmth
- Reinforcement — EVA (20% recycled): foot support and body alignment
- Heel pad — EVA (20% recycled): flat surface for a better fit in the ski boot, plus cushioning
- Base — dual-density EVA rubber: cushioning
