Functional shoe including weight support unit

Abstract

As described above, just as a person inserts his/her toes into a space under furniture and does sit-ups by using the force of the toes, a functional shoe of the present invention provides a portion into which an instep and a toe base portion are inserted on the functional shoe to use the force of the toe base portion which may exert the greatest force from among portions of a foot, thereby adding momentum. Accordingly, a wearer may further use the force of the instep and the toe base portion to support weight. That is, when a batter hits a baseball in a baseball game, an instep of the batter including a toe base portion may be inserted into a weight support unit to support the weight of the batter, thereby adding forces of the instep and the toe base portion the weight of the batter. When a golfer makes a tee shot in a golf game, an instep and a toe base portion may be inserted into a weight support unit provided on a golf shoe to support weight, thereby obtaining a distance gain as much as forces of the instep and the toe base portion of the golfer. Also, the functional shoe including a weight support unit consisting of a weight support part and an auxiliary support band may be applied to a golf shoe which helps a golfer to achieve balance in a finishing posture during a golf swing or a mountain climbing shoe or a combat boot which helps a wearer to achieve balance on an ascent. For example, when the functional shoe of the present invention is applied to a golf shoe, the golf shoe is structured to conform with a foot not to obstruct the upward movement of toes to pull ligaments, which connect the toes and an instep of a grounded foot, to achieve balance when weight is shifted backward in a finishing posture during a golf swing, and structured to allow the instep and a toe base portion to be inserted into the weight support unit formed on an instep portion to achieve balance in a finishing posture during a golf swing which is very important in a golf game, thereby improving performance. Also, for example, when the functional shoe is applied to a mountain climbing shoe or a combat boot, when a wearer climbs a slight slope by inserting an instep including a toe base portion into the weight support unit formed on the instep portion to achieve balance when weight is shifted or climes a steep slope by holding a rope or a wire with the arms and hands to support weight, the burden of the arms and hands may be reduced by using the weight support unit into which the instep including the toe base portion is inserted and supporting the weight based on the fulcrum and level effect
