Description

  The present invention relates to a shoe suitably used as an exercise shoe such as a walking shoe, a golf shoe, a tennis shoe, and more particularly, to a shoe having a function of supporting the movement of a foot during exercise.

  2. Description of the Related Art Conventionally, shoes having a function of supporting foot movements in exercises performed while wearing shoes such as walking have been proposed. For example, in Patent Document 1, as a shoe capable of improving a fitting function and a walking support function for a shoe, the shoe is in contact with the user's sole tip at a position corresponding to the user's sole tip. It has been proposed to wear an insole (insole) provided with a detachable foot tip support that restricts the user's foot from moving forward in the shoe (Claims 1 and 5). .

JP 2008-23290 A

  In walking, it is said that it is a good form that the foot walks so as to kick out the ground backward with a toe after landing from a heel. However, the shoe of Patent Document 1 has a function of restricting the user's foot from moving forward in the footwear as a function of supporting the movement of the foot in the exercise performed while wearing the shoe. It did not have a function to support the exercise to kick the ground backward, but the function to support walking was insufficient.

  The present invention has been made in view of the above circumstances, and has an object of providing a shoe having a function of supporting exercise to kick the ground backward with a toe and having a sufficient exercise support function. To do.

  In order to achieve the above object, the present invention provides an outsole, a midsole, an insole board, and an insole, wherein the insole is more easily deformed by the pressure of a foot of a shoe user than the insole board. There is provided a shoe characterized in that a concave portion is formed in a toe portion of a laminate of a sole and the insole board, and an elastic repellent body is disposed in the concave portion. Here, the toe portion of the laminate of the midsole board and the midsole refers to a portion where at least the tip of a toe of the laminate is indirectly in contact via the insole.

  The shoe according to the present invention is arranged in the recess formed in the toe portion of the laminated body of the midsole and the midsole board, so that the elastic repellent body is disposed, so in the exercise performed by wearing shoes such as walking, Due to the elastic effect and shape effect of the repulsion body, it is possible to support the movement of kicking the ground backward with the toes of the foot. That is, the shoe repellent according to the present invention has a repulsive force and is disposed in the recess formed in the toe portion of the laminate, so that the user of the shoe can repel the rebound during walking or the like. When the body is pushed with a toe, the toe can be strongly kicked backwards with the toe. In this case, the above-mentioned repulsion body is not covered with an insole board that is more difficult to deform due to the pressure of the foot of the shoe user than the insole, but is covered with an insole that is more easily deformed by the pressure of the foot of the shoe user than the insole board. Therefore, when the user of the shoe presses the repellent body with a toe through the insole during walking or the like, the repellent body is easily deformed, and the above-described effects can be obtained with certainty.

  In the present invention, the insole is preferably formed of a resin having a hardness lower than that of the midsole board, whereby the above-described effects can be obtained satisfactorily.

  Further, in the present invention, the repellent body is preferably formed of a resin having a lower hardness than the insole board, whereby the above-described effects can be obtained satisfactorily. In this case, the hardness of the repellent body may be higher or lower than the hardness of the insole, and may be the same as the hardness of the insole.

  In the present invention, the shape of the recess formed in the toe portion of the laminate of the midsole and the midsole board is not limited, and can be various shapes as shown in the embodiments described later.

  The shoe according to the present invention has a function of supporting the movement of the foot in the exercise performed while wearing the shoe. Examples of the exercise include walking, jogging, running, golf, tennis, and the like. Such shoes are particularly preferably used for walking shoes, golf shoes, tennis shoes and the like.

  The shoe according to the present invention has an excellent exercise support function because it can support the movement of the foot that kicks the ground backward with a toe during exercise performed while wearing shoes such as walking.

  The shoe sole (for left foot) 10 of the shoe of this example is formed by laminating an outsole 12, a midsole 14, an insole board 16, and an insole (insole) 18 in order from the bottom. The outsole 12 is a part in contact with the ground, the midsole 14 is a part laminated on the outsole 12, the insole board 16 is a part laminated on the midsole 14, and the insole (insole) 18 is an insole Parts stacked on the board 16.

  In the shoe sole 10 of this example, the outsole 12 has a higher hardness than the midsole 14, and the midsole board 16 has a higher hardness than the midsole 14 and the insole 18. The insole 18 is more easily deformed by the pressure of the foot of the shoe user than the insole board 16. Further, in the shoe sole portion 10 of this example, a concave portion 22 having a substantially elliptical longitudinal and transverse cross section is formed at the toe portion of the laminate 20 of the midsole 14 and the midsole board 16. A resilient body 24 having elasticity is disposed on the surface. In FIG. 2, reference numeral 26 denotes an upper.

  In this example, examples of the material of the outsole 12 include rubbers such as butadiene rubber, isoprene rubber, styrene / butadiene rubber, polyurethane, ethylene vinyl acetate (EVA), and the like, but are not limited thereto. It is not something.

  Examples of the material of the midsole 14 include, but are not limited to, EVA, polyolefin foam, polyurethane foam, thermoplastic polyurethane, rubber, and the like. The outsole 12 and the midsole 14 may be made of the same material.
