Women's ballroom dance shoes to prevent bunions

Abstract

To provide ballroom dancing shoes for preventing hallux valgus for women, preventing the development of hallux valgus even when dancing ballroom. [Solution] The line a on the big toe side of the shoe is made nearly straight, not pointed, to prevent valgus of the big toe. Furthermore, a thong 2 is attached to the insole 1, and this thong supports most of the body weight, reducing the burden that has previously been placed on the toes. In standard shoes, the toe area 3 is made sufficiently wide, and in Latin shoes, the toe cap is made sufficiently wide.

Description

[Technical Field]

[0001] This invention relates to women's shoes used for ballroom dancing, and to dance shoes with a structure that helps prevent or slow the progression of hallux valgus. [Background technology]

[0002] Women's ballroom dancing shoes inevitably have heels, but in heeled shoes, most of the weight is placed on the toes. Conventional women's ballroom dancing shoes, both standard and Latin, tend to be designed with a pointed triangular toe, which makes it easy for the big toe to turn eversion and the little toe to turn inward. Ballroom dancing is a strenuous activity, which can cause deformation of the metatarsophalangeal joint, leading to the onset and progression of hallux valgus. In particular, a high percentage of Japanese people have feet with the longest big toe, which has meant that traditional shoes based on Western foot design concepts are not very compatible. The inventor is a dermatologist who sees many patients with hallux valgus every day. Elderly people who engage in ballroom dancing tend to be healthy and energetic, but he felt it was disappointing that many of them gave up dancing due to the worsening of their hallux valgus and the pain in their feet. Common "bunion shoes" are designed for deformed feet, but are not designed to slow the progression of bunions. The idea was to create shoes that would prevent bunions from developing even when dancing ballroom.

[0003] The purpose of this invention is to reduce pressure and weight on the toes, including the big toe, in women's ballroom dancing shoes, thereby preventing or slowing the progression of hallux valgus.

[0004] The ballroom dance shoes of the present invention are characterized by the following configuration. 1. Attach the thong to the insole A component equivalent to the thong of a zori sandal is provided inside the front part of the shoe, allowing the thong to support most of the wearer's weight. 2. Straightening of the big toe The line around the big toe on the shoe body is shaped in a straight line to fit the "longest big toe" foot shape that is common among Japanese women. 3.Application development The shoes with the above configuration can be used for both standard and Latin dance.

[0005] The present invention provides the following advantages: - It is suitable for the foot shape common among Japanese women and is effective in preventing or slowing the progression of hallux valgus. The thong now supports most of the weight that was previously placed on the toes, reducing the strain on not only the big toe but all the toes, and preventing deformation of the metatarsophalangeal joints. Maintains balance in the toes and improves comfort even during the intense exercise of ballroom dancing. - It can be used with both standard and Latin shoes, allowing for a wide range of applications.

DETAILED DESCRIPTION OF THE INVENTION

[0007] The thong 2 is attached to the insole 1 like a pair of sandals.

[0008] Move line a on the big toe side of the shoe closer to a straight line.

[0009] Since the thong 2 supports most of the body weight, the toe part 3 of the standard shoe does not need to support the body weight and is designed to not hurt when stepped on. It is made taller and wider so as not to compress the toes. The toe ornament 4 of Latin shoes, omitted in Figures 3 and 4, is not necessary if the thong 2 is wide enough to withstand the weight. If it is made, it should be large so as not to press too hard on the toes. The toe ornament 4 is not made to support the weight of the foot, but merely as a support or decoration for the thong 2. [Example]

[0010] An embodiment will be described below with reference to the attached screen shots. As shown in Figure 2, attach the thong 2 to the insole 1. Furthermore, as shown in Figure 3, the line a from the metatarsophalangeal joint to the big toe on standard shoes should be made closer to a straight line. Figure 1 shows the standard shoe shown in Figure 3, with the insole shown in Figure 2 used. The toe part 3 is made slightly taller and wider so as not to compress the toes. The thong 2 supports the weight of the foot, so the toe part 3 is there to prevent pain when stepped on, and should not be designed to compress the toes.

[0011] As shown in Figure 6, attach the thong 2 to the insole 1 of the Latin shoes. The toe ornament 4 shown in Figure 5 is not necessary, but if you do make one, make it taller and wider so as not to compress the toes. If there is no toe decoration 4, the entire weight is supported by the thong 2, so it is better to make the thong wider.

[0012] In the example of standard shoes, the thong 2 is passed through a horizontal hole 5 within the frame of the insole 1, just like regular geta or zori sandals, but in the example of Latin shoes shown in Figure 6, the thong 2 protrudes beyond the outer frame of the insole 1 and is glued between it and the outsole 6. Either way is fine, as long as the thong 2 functions to support the wearer's weight. Figure 7 shows a top view of a women's Latin shoe with a straight line a on the big toe side. A thong 2 is attached to an insole 1. Unlike conventional shoes that cause the big toe to evert and little toe to evert when worn, the shoes of this invention do not put pressure on the toes.
