Sock capable of providing additional protection for an ankle joint

Abstract

A sock includes a sock body with a leg section and a foot section. The leg section has a cuff that defines a foot opening for insertion of a foot of a wearer. The foot section is connected to the leg section, and includes a toe section, a heel section, a sole section, and an instep section. The leg section has a back segment that faces away from the toe section and that is formed with an opening. The sock body is convertible when worn on the foot to an ankle protecting state, in which the leg section is folded down so that the cuff surrounds the foot section between the toe section and the heel section and so that the heel section extends through the opening, such that the leg section is able to provide additional protection for an ankle joint of the foot.
