A favorite of those with low arched feet, the Sidas 3 Feet Winter Low Insole offers an excellent amount of support in a tailored and lightly insulated frame. A thin layer of aluminum film adds an element of barely-there insulation that—when combined with a large foam pad and an anatomical construction—delivers a complete blend of warmth, comfort, support, and precision. Equipped with Sidas’ 3 Feet technology for an optimized distribution of pressure, the 3 Feet Winter Low Insole prevents foot fatigue with an exceptionally tailored approach to support.
