An insole includes a layer of foam material which is infused with an aloe extract to provide relief to dry, cracked or itchy feet, facilitate cell renewal and reduce odor. The aloe extract is typically in the form of aloe barbadensis leaf juice. The foam material typically includes ethylene vinyl acetate foam although other foams may be used, such as rubber foam, latex foam, polyethylene foam and polyurethane foam.
