The Footprint Kingfoam Elite High Classic insoles are suitable for all foot types and are designed specifically for individuals with mid to high arches. Featuring a 10 mm thick heel and a 5 mm toe, these insoles provide the highest level of heel protection among our products. In lab testing, they absorb 91% of impact energy, significantly outperforming other performance insoles, which only absorb 53% (ASTM F 1614 – 1999). Made from a proprietary material used by NASA for protecting sensitive electronics on the International Space Station (ISS), these insoles ensure exceptional durability and support.
