Abstract
A sock may include a first low-elasticity area disposed on a dorsal portion of the foot, the first low-elasticity area being band-shaped and having a lower elasticity than other areas of the sock. The first low-elasticity area may include a curved ankle portion and an end portion, the end portion being disposed below the curved ankle portion and extending to the base of the toes. The end portion may be positioned within a range from the base of the third toe to the base of the small toe. A center line in the course direction with respect to the width of the first low-elasticity area may gradually shift toward the side of the small toe in the course direction. Preferably, the first low-elasticity area applies a force that raises the side of the fifth toe toward the ankle curve portion thereby providing a resistive force against the ankle twisting inwards.
