A footgear barrier and a foot covering incorporating a footgear barrier. The footgear barrier is sized and shaped to be placed around a user's ankle and over the footgear, such as an athletic shoe, to block the gaps between the user's ankle and the footwear and reduce the amount of debris that may pass through the gaps. The footgear barrier may be incorporated within a foot cover such as a sock, such that the barrier is secured within an upper portion of the sock.
