Sidas 3Feet Eco Winter Mid
The Sidas 3Feet Eco Winter Mid is an anatomically shaped winter insole designed for ski boots, touring boots, Nordic boots, and ice skates. Built specifically for medium-arch feet, it offers stable support and balanced pressure through its EVA construction. Compared to the previous generation, the heel has been slightly narrowed for a more precise fit in modern performance ski and skate boots.
A woven polyester top sheet combined with Evamic insulated foam helps retain warmth and keep feet comfortable during long days in cold environments. The Sidas 3Feet system provides arch support tailored to the natural foot shape—preventing excessive pushing into the arch while maintaining proper alignment.
Manufactured with eco-conscious materials, the insole reduces production impact, and Sidas donates one euro per pair sold to forest restoration projects via the Sidas World foundation.
