Description

Shoes with improved fit}

The present invention relates to shoes with improved fit.

In general, shoes reduce the shock transmitted through the feet while walking and protect the feet from various risk factors, and are manufactured in various forms to suit the purpose, such as walking shoes, running shoes, and hiking shoes.

Shoes that were developed to protect the feet are having a negative effect on the feet as development progresses in a direction that emphasizes design rather than function.

For example, in the case of running shoes or high heels, the front width is narrow and pointed, and the heel is formed high, so that the body weight is biased in the direction of walking when walking.

In other words, existing shoes have shoe soles that are low on the front toe side and high on the rear heel, so the center of gravity is inevitably tilted towards the front of the body. This imbalance in the center of gravity causes the body weight to be transferred to the front of the sole when walking, so the center of gravity is lowered. This leans forward.

Accordingly, conventional shoes do not distribute the body weight evenly over the entire sole and cause the body weight to shift forward, which breaks the balance of the feet, putting a strain on the joints of the soles, ankles, spine, etc. during walking, thereby increasing foot fatigue.

In addition, the imbalance of body weight due to an imbalance in the center of gravity causes problems such as deformation of the feet, causing diseases such as hallux valgus in the toe joints, and putting strain on the spine, causing various spinal diseases such as disc problems.

In addition, a third extension cover is disposed at the upper end of the second detachable part 13 through Velcro and attached to the inner surface of the third detachable part to conceal the third zipper, and at the lower end of the third detachable part through Velcro. A fourth extension cover may be attached to the outer surface of the detachable portion 13 and disposed to conceal the third zipper.

According to this embodiment of the present invention, the thickness of the front heel 221 and the thickness of the heel 222 are formed to be 5 mm or less, and the relative ratio of the thickness of the heel 222 to the thickness of the front heel 221 is 1:1 or more. It is set to 1:1.5 or less, so the deviation between the front heel 221 and the heel 222 is minimized, so walking like barefoot is possible, enabling correct walking, and is stably supported on the ground to prevent vertically applied loads from falling on the ground. It reduces fatigue while walking by dispersing it, and stabilizes the body's balance and center of gravity, making foot correction and spinal correction possible.

Although embodiments of the present invention have been described in more detail with reference to the accompanying drawings, the present invention is not necessarily limited to these embodiments, and various modifications may be made without departing from the technical spirit of the present invention. . Accordingly, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention, but are for illustrative purposes, and the scope of the technical idea of the present invention is not limited by these embodiments.
