Summary of the Invention

Problems to be Solved by the Invention

[0004] However, when a conventional insole having a shoehorn part is placed in shoes that a user normally wears, there is a problem that the shoes feel tight due to the thickness of the shoehorn part, and the wearing comfort deteriorates.

[0005] Therefore, an object of the present invention is to provide an insole that can improve the ease of putting on shoes while maintaining good wearing comfort.

Means for Solving the Problems

[0006] The above object of the present invention is achieved by an insole including a heel contact part that is arranged to contact the insole of the shoe and against which the user's heel abuts, and a heel guiding part that is provided so as to rise from the rear edge part of the heel contact part and guides the user's heel, wherein the heel contact part and the heel guiding part are integrally formed so as to be elastically deformable, and the heel contact part has a notch at a position corresponding to the center of the user's heel.

[0007] In this insole, it is preferable that the notch opens at the front edge of the heel contact portion.

[0008] Furthermore, it is preferable that the heel guide portion includes an auxiliary notch formed in the center in the width direction so as to face the rear edge of the heel contact portion. In this configuration, it is even more preferable that the notch and the auxiliary notch are in communication with each other. [Effects of the Invention]

[0009] According to the insole of the present invention, it is possible to improve the ease of putting on shoes while maintaining good comfort. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0011] Embodiments of the present invention will be described below with reference to the accompanying drawings. Figure 1 is a perspective view of an insole according to one embodiment of the present invention. As shown in Figure 1, the insole 1 of this embodiment comprises a heel contact portion 2 and a heel guide portion 3 that is provided to stand up from the rear edge portion 2a of the heel contact portion 2. The heel contact portion 2 and the heel guide portion 3 are made of EVA resin, urethane resin, elastomer, rubber material, cork material, etc., similar to conventional insoles, and are integrally formed so as to be elastically deformable.

[0012] The heel contact portion 2 is formed in a flat shape with a size that allows it to contact almost the entire heel portion, which is the part of the heel that is closer to the arch of the user's foot, and is positioned to contact the upper surface of the insole of the shoe.

[0013] The heel rest portion 2 is provided with a notch 4 at a position corresponding to the center of the user's heel. The notch 4 extends forward from near the center of the heel rest portion 2 and is formed to open into the front edge portion 2b of the heel rest portion 2. The width of the notch 4 may be constant, or it may be formed to widen in a tapered manner toward the front.

[0014] The heel guide portion 3 is formed in a curved shape by rising from the arc-shaped rear edge portion 2a of the heel contact portion 2, and guides the user's heel downward along the curved surface when the user puts on the shoe. The upper part of the heel guide portion 3 is formed to be narrow in width to facilitate elastic deformation.

[0015] As shown in Figure 2(a), the insole 1 having the above configuration is positioned at the rear of the shoe S such that the heel guide portion 3 extends upward along the heel curve of the shoe S and protrudes diagonally backward from the opening O. By sliding the heel of the user's foot, indicated by the dashed line, along the heel guide portion 3, the shoe S can be put on smoothly.

[0016] In the state where the shoe S is fully worn, the central part of the user's heel fits into the notch 4 of the heel contact part 2, resulting in the notch 4 expanding in the width direction. As shown in Fig. 2(b), the heel contact part 2 rises along the side surface of the shoe S, and the inside of the shoe S is pushed and expanded in the width direction by the heel contact part 2. Thereby, the sense of tightness of the user associated with the use of the insole 1 is alleviated, and a good wearing comfort can be maintained.

[0017] As described above, one embodiment of the present invention has been described in detail, but the specific aspects of the present invention are not limited to the above embodiment. For example, as shown in Fig. 3, the heel support interior 3 may be configured to include an auxiliary notch 5 formed at the center in the width direction so as to face the rear edge portion 2a of the heel contact part 2. According to this configuration, since the auxiliary notch 5 is formed at a position adjacent to the heel contact part 2, when the user wears the shoe, the heel support interior 3 is deformed and the notch 4 is more likely to expand in the width direction, so that a good wearing comfort can be easily maintained. The notch 4 and the auxiliary notch 5 shown in Fig. 3 may be formed to communicate with each other as shown in Fig. 4, whereby the heel contact part 2 can be deformed more easily. In Fig. 3 and Fig. 4, the same reference numerals are assigned to the same components as those in Fig. 1 (the same applies to the following drawings).

[0018] The insole 1 provided with the auxiliary notch 5 shown in Fig. 3, in the state where the user has finished wearing the shoe as shown by the two-dot chain line in Fig. 8, since the rear side C of the user's heel bone fits into the auxiliary notch 5, the heel support interior 3 can relieve the force that tries to push the user's foot forward, and can alleviate the sense of tightness inside the shoe. The same applies to the insole 1 shown in Fig. 4.

[0019] <! The shape of the notch 4 is not particularly limited. For example, as shown in Fig. 5, it may be formed in an elongated hole shape with the longitudinal axis in the front-rear direction. Thus, even if the notch 4 is a through hole, it is possible to maintain good wearing comfort by the elastic deformation of the heel contact part 2. The notch 4 shown in Fig. 5 may be formed to open to the front edge portion 2b of the heel contact part 2 through a constriction part 4a narrower than the short-axis length as shown in Fig. 6, whereby the elastic deformation of the heel contact part 2 can be promoted.

[0020] The shape of the heel support inner part 3 is not particularly limited. For example, as shown in FIG. 7, by forming a constricted portion 3a in the width direction of the heel support inner part 3 and forming a recessed portion 3b at the center of the upper edge of the heel support inner part 3, the ease of putting on the shoe can be further enhanced.
