Image Number 4 for United States Patent #6334222.
A sock for preventing athlete's foot includes sheaths at the toe portion of the foot that can reach, cover, and fit into areas between toes. The sheaths can absorb moist, greasy and other secretions between toes and keep skins in the area dry. This prevents microscopic fungi from thriving between toes. The sheath portion remains integral with the rest of the sock that may also include a foot body, heel, ankle, and leg engaging portion.
