To solve a problem that anyone often experiences to sweat on feet when wearing shoes, the feet get stuffy or emit malodor to make the wearer uncomfortable, insoles with high hygroscopic property and ones containing activated carbon in fibers are marketed, those have a prescribed effect on the stuffiness and malodor prevention, however, are little expectant for preventing and curing the foot ringworm.

Raw aloe leaves are crushed into a liquid, and a hygroscopic material is immersed therein to be impregnated with the medicinal components of the aloe, is dried and is used as an insole. This insole has the hygroscopic property, retains a foot comfortable, prevents the malodor, and cures and prevents the foot ringworm. For satisfying the function as the insole, a nonwoven fabric or other reinforcing materials may be attached to the front surface, back surface, or inside.
