3D shell
The 3D shell is the firm anatomical base of a Sidas insole with a heel cup. It supports the arch, keeps the foot in the correct position and improves stability when walking and during sport.
Insoles Sidas 3D XC Nordic
These insoles have been developed specially for cross-country skiing, for both classic technique and skating. Leading cross-country skiers were involved in the 2-year development. They perfectly support the plantar arch, distribute pressure and, thanks to the propulsion pad in the forefoot, support the skier's push-off. The surface is antibacterial, washable with water and abrasion-resistant.
The insoles have a narrower shape for narrow to medium-wide feet. For wide feet, Sidas recommends the 3Feet Eco Winter or Custom XC insoles.
Trim the insole to match the original insole in your shoe. Wash it only with mild soap and a brush, do not dry it on a radiator; use a forced-air shoe dryer for drying.
