Abstract: A sock is described which can be worn in a boot or other situation where an ordinary sock is likely to sag, wherein the sock is constructed to resist such sagging. The sock includes an elastic sock body and a strip-shaped stiffener sewn to the outer surface of the sock body. The stiffener extends along the front of the sock body on the upper sock portion which surrounds the leg of the wearer, and on the lower sock portion that surrounds the foot of the wearer. The stiffener extends in a loop above the top of the sock body to form a finger-receiving loop that can be used to pull up the sock.
