Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to shoes, and is particularly suitable for shoes worn during strenuous exercise, which improves the degree of contact between the upper surface of the heel portion of the shoe and the lower surface of the heel of the foot, and at the same time This is a device that effectively prevents the foot from sliding forward and backward, left and right, and from turning in and out.

Conventional technology Conventionally, the method of tightly fitting the shoe and the foot has been quite effective in the front half of the shoe using shoelaces, but unfortunately it is not as effective from the foot of the shoe to the heel. There were almost no ideas found. Therefore, when the heel is raised, a slight gap or looseness between the lower surface of the heel and the upper surface of the heel part of the midsole of the shoe not only reduces the sense of unity between the foot and the shoe, but also reduces the feeling of lightness. During footwork that applies rapid braking in the front-back direction or in the medial-lateral direction, there is a risk of injuring the toes of the foot or even causing a sprain.

For this reason, deep shoes such as mountain climbing shoes and basketball shoes, which cover the upper part of the ankle with the upper part of the foot, were created, and some wearers wrapped the shoelaces around the ankle twice. Methods such as attaching the shoes and tying them have been taken, but these are not sufficient preventive measures, and the reality is that there are still very few innovative ideas for shallow shoes.

In the past, in the above-mentioned deep shoes, a U-shaped strap was attached to the inside of the heel part, with the opening facing toward the toes and wrapping around the heel part and neck part of the foot.
Connect the tightening cord to the tip of one side of the sewn cloth, and

No. 18900), a device that tightens the ankle toward the heel on both sides of the opening of the shoe body (Japanese Utility Model Publication No. 1983-31803), and a leather band between the front and back sides on both sides of the instep. The lower end is fixed to the bottom, and the upper end is tied with a rubber string (as proposed by Utility and Public University).
14-21379) has been made.

Problems to be Solved The publicly known athletic shoes devised in Utility Model Publication No. 10-18900 are as follows:
Wrap the U around the heel and neck of the foot on the inside of the heel.
Open the letter-shaped tightening cloth toward the toes,
Since the base and rings of the strap are attached to the tips on both sides and tightened, the range of the tightening action is spread over the entire periphery of the heel and neck of the foot. That is, the tightening force is also exerted in the horizontal direction along the neck, and the force is not concentrated in an effective direction. Therefore, although the U-shaped tightening cloth is separated from the upper, the effect is almost the same as that of attaching and sewing the base of the tightening strap and the folded loop to the corresponding part of the upper. There are drawbacks that can only be obtained. In addition, the idea of Utility Model Publication No. 14-21379 was to sew a second fastener to both sides of the cuff of the shoe body, and the idea of Utility Model Publication No. 14-21379 was to attach a second fastener to the upper side of the shoe. Leather bands are integrally sewn on both sides of the upper part for the purpose of preserving the shape of the upper part, and both have the same drawbacks as above. Therefore, during fast and intense footwork, although the shoe may have the effect of preventing the foot from sliding forward inside the shoe, it is difficult to effectively prevent side-to-side wobbling or internal and external rotation. Furthermore, there are also drawbacks such as the difficulty in attaching the device to shallow type shoes.

Means for Solving the Problems The present invention provides a shoe consisting of an upper, a middle sole, and an outer sole, and having a first fastener at the front of the upper. consisting of a tightening member, one end of each of the tightening members being inserted and fixed between the lower edges of both sides of the rear inner surface of the upper and the lower surface of the midsole, and the intermediate portion extending free from the upper. These shoes are characterized by having ends that are connected and fixed to each other at the front upper part of the large bones of the wearer's ankles, and are made to fit closely to the feet.

Function The present invention provides a second area extending from the inside of the shoe corresponding to the rear lower part of the calcaneus of the wearer's ankle to the front upper part of the large ankle bone.
The second fastener is used to tighten the space between the shoe and the large bones, thereby increasing the degree of contact between the upper surface of the heel part of the shoe's midsole and the lower surface of the heel of the wearer's foot. be.

Example In Fig. 1, 1 is the upper part, 2 is the midsole part, 3
is an outer sole, 4 is a tongue piece, and a first fastener (not shown) such as a shoelace is attached to the front opening on the upper front surface of the upper part 1. Incidentally, in the case where the first fastener uses a fastener that connects surfaces to surfaces, the tongue piece is unnecessary.

5 is a second fastener, which includes two fastening members 6,
Consists of 7. As shown in FIG. 2, the tightening members 6 and 7 are made by cutting a relatively thick cloth made of cotton, nylon, or other similar materials into strips, and attaching them to the overlapping parts 6' and 7', respectively. These tightening members 6, 7 are made by attaching fasteners 8, 9 that are joined face to face.
The base parts 6'' and 7'' of the upper part 1 are inserted and fixed between the lower edges of both rear sides of the upper part 1 and the lower surface of the midsole. In addition, the tightening members 6 and 7 are oriented diagonally upward so that the tightening members 6 and 7 overlap at the front upper part of the large ankle bone 10 of the wearer, with the base parts 6'' and 7'' fixed. put.

The wearer puts his/her foot into the shoe, pulls the heel toward the rear of the shoe, pulls up the tightening members 6 and 7, and secures them by overlapping them on the front instep of the foot, and then using the tongue piece 4 over the top of the shoe. Then, use the first fastener, that is, the shoelace, to tighten the laces in the usual way. As a result, the tightening member 6,
In the ankle skeleton diagrams shown in FIGS. 3 and 4, 7 extends obliquely upward from the rear lower part of the calcaneus 11 toward the front upper part of the giant bone 10, as shown by the dotted line. That is, the middle sole part 2 serves as a contact plate, and the calcaneus 11
This means that both the big bones and the big bones 10 were all in one place.

Effects of the Invention The present invention applies a tightening force directly and intensively across the tightening member from the rear lower part of the calcaneus to the front upper part of the giant bone, so that The close contact with the lower surface is high, and when you tip-toe or raise your foot, the feeling of unity between the shoe and foot and the lightness are exquisite. In addition, as a result of integrating the entire heel part including the midsole of the shoe, the calcaneus, and the large bones, it prevents the foot from sliding forward, to the left or right, and from rotating inward and outward, even during fast and intense footwork. Protect your feet from ankle sprains. Furthermore, it has a ripple effect on the front half of the foot, which is linked to the large bones and calcaneus, by preventing slippage and shaking, giving the wearer overall comfort and stability. However, this device does not impose an extreme economic burden on the wearer, and is extremely easy to manufacture.
