Abstract: Disclosed herein is a heel protector including a body member made of a flexible fabric material for being worn on the feet and an inner pad member coupled to an inside of the body member for accommodation to an area where a heel is located when the heel protector is worn. Both distal ends of a longitudinal direction of the inner pad member are coupled to the body member, and two areas of the inner pad member accommodated to both lateral sections of the heel are coupled to the body member, such that the inner pad member can relatively slide in relation to the body member when the heel protector is worn. Friction generated on the heels while walking can be subdued by the inner pad member to thereby prevent formation of calluses or blisters, and manufacturing process can be simplified to reduce the manufacturing cost.
