Bauerfeind's ErgoPad Ski and Skate insoles keep your feet stable yet flexible during winter sports in which foot and joint pain is common. They are used for improved transfer of force to the skis or skates. ErgoPad Ski and Skate heel cup surrounds the heel and provides support for lateral movements, the toe bank stretches the small toes for better contact between the feet and the shoes. Weightflex technology supports the natural movement of the feet, while the thermoregulating top cover protects against the cold. The flexible high-performance orthotic core with weightflex technology is perfectly designed for the sport-specific loads and movement patterns. The integrated X-shaped component of the core has a positive effect on the dynamics and torsional stability of the feet. The side sections, which vary in elasticity, guide the forces that arise over two pivot points. The mutual exchange of force supports the natural heel-to-toe movement resulting in active foot guidance and gait correction. Orthotic core is partially coated in high-quality polyurethane soft foam. Material: Fabric, Polyurethane.
