These insoles feature 3 layers of materials: microfiber, carbon and gel.
The bottom gel layer provides the cushioning and shock absorption your feet, knees and back need. The active carbon layer eliminates moisture and odor to keep your feet fresh wherever you are. It also has a eucalyptus scent.
They are often used with any type of shoe and their high level of shock absorption makes them an extremely comfortable option for all types of feet.
