SOCK

PROBLEM TO BE SOLVED: To solve the problem that a sprain-preventative sock do not provides a resistive force against the ankle twisting inwards, and inversion sprain preventative effect is not enhanced. SOLUTION: The sock may include a first low-elasticity area 1 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 1 may include at least a curved ankle portion 1d and a lower end portion, the end portion being disposed below the curved ankle portion 1d, and extending to the base of the toes so that a center line C 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. The end portion 1b may be positioned within a range from the base of the third toe to the base of the small toe. The first low-elasticity area 1 applies a force that raises the side of the fifth toe toward the ankle curve portion 1d thereby providing a resistive force against the ankle twisting inwards, thereby making it possible to effectively prevent inversion sprains.
