JP3238879U - Footwear soles that train the muscles of the toes - Google Patents

Abstract

[Problem] To prevent the collapse of the lateral arch of the foot, floating toes, hallux valgus, and coldness of the toes caused by the weakening of the muscles of the toes, to use and train the muscles of the toes naturally just by wearing them. We provide a sole that can be used. SOLUTION: The sole is covered with a brush-like material densely packed with fine projections made of synthetic resin in a portion corresponding to the sole of the foot from the toe to the metatarsal bone. As a result, every time you step on footwear using this sole, the sole sinks in, creating a state in which the muscles of the foot are used without being conscious of it, and the muscles of the toes can be naturally trained.

Description

The present invention relates to a footwear sole for training toe muscles.

Modern footwear such as shoes and sandals have soles that are stable in a fixed shape, so they protect the feet well, and even when wearing them and walking, the muscles of the toes cannot be used sufficiently. As a result, the muscles of the toes, which should be strengthened by walking, are weakened. Weakening of the muscles of the toes has given modern people various problems such as collapse of the lateral arch of the sole of the foot, floating toes, hallux valgus, and coldness of the toes. Many people have already considered such a problem as a problem, and various sandals and the like have been proposed so far.

Utility Model Registration No. 3202224

Sandals and soles that have been devised so far have worked on the toes by stimulating and stretching the muscles of the foot by adding dents and protrusions to the part that touches the sole of the foot. However, this method does not move the toe muscles, and none of them lead to strengthening of the toe muscles. In response to this, the present invention proposes a sole that enables to forcibly move muscles according to the conventional muscle training method of "moving muscles to train muscles". You are trying to build muscle.

In this invention, a brush-like material densely packed with thin projections made of synthetic resin is laid on the sole of the sole of the foot from the toes to the metatarsal bones, so that each time the footwear is stepped on, the brush is brushed. The protuberances in the shape of the legs sink in, creating a state in which the muscles of the legs can be used without being conscious of it. In addition, this invention uses a resilient material called a brush made of synthetic resin, so the moment you lift your foot, the brush will rise again, and the next time you step on it, it will sink again. It makes it possible to continue doing exercise that trains muscles just by walking.

As mentioned above, the use of the present invention allows you to repeatedly step on the sinking ground and exercise your toe muscles. This reproduces the state of walking barefoot on dirt and sand, and the foot naturally uses the muscles of the toes to grasp the unstable ground.

Of the entire length of the sole, the sole of the foot from the tip of the foot to the metatarsal bone, at least about 40% of the length from the toe, is made of synthetic resin, as shown in 1 of Figures 1 and 2. It is a sole in the form of a brush-like material with densely packed thin protrusions.

Each projection (2 in Fig. 2) that constitutes the brush-like material has a diameter of about 1 mm to 3 mm, a height of about 8 mm to 12 mm, and a height of 10 mm including the synthetic resin base. It must be made of a material (silicon, etc.) with a thickness of ~14mm that sinks when the foot is stepped on and rises immediately when the foot is lifted.

To prevent the brush-like mat from slipping, the synthetic resin protrusions together with the base are adhered to the base of the sole (4 and 5 in Fig. 2).

The heel portion of the sole (3 in FIG. 2) is desirably 10 mm to 20 mm higher than the sole under the toes in order to easily apply force to the toes.

When this invention is used with sandals or slippers, the image is as shown in FIG. The brush-like sole is expected to have problems such as easy accumulation of dirt and excessive stimulation to the feet, so it is expected to be commercialized with a thin, soft cloth or the like.

Claims (1)

In the sole, the part that corresponds to the sole of the foot from the toe to the metatarsal bone has a structure in which a brush-like substance with densely packed thin protrusions made of synthetic resin is laid. . The brush-like part is made of a soft and elastic material such as silicon.
