Sidas 3Feet Eco Winter High
Give your feet stability, warmth, and comfort during winter sports. Sidas 3Feet Eco Winter High are anatomically shaped insoles designed specifically for feet with high arches. Ideal for ski boots, ski touring boots, and cross-country boots, they also fit perfectly in skates. The EVA foam construction provides optimal arch support, improves pressure distribution, and stabilizes the foot with every movement. Evamic Insulated foam combined with a finely woven polyester cover keeps feet warm even in extreme conditions. Thanks to the tapered heel shape, the insoles fit perfectly into modern sports ski boots, where they ensure maximum contact with the boot and energy transfer during downhill skiing.
