Abstract: An easy-on sock having a split opening extending down the middle of the top surface of the sock from the lower leg portion to the toe pocket of the sock is provided. An extension flap, used to close the split, is connected along one edge of the split and extends substantially the full length of the split. Hook and loop closure strips are attached on the free edge of the extension strip and along the other edge of the split to enable the extension flap to be folded over the split and secured to the opposing hook and loop closure strip. In one embodiment, an insert flap is additionally connected to the other edge of the split, opposite the extension flap. A hook and loop type connector is attached to the outer surface of the insert flap and a mating hook and loop type sizing strip is attached to a corresponding location on the inner surface of the extension flap. Thus, the sock may be closely fitted to the foot of the user by first mating the hook and loop type closure strips and/or connectors.
