Description

[Detailed Description of the Invention] A. Industrial Applications The present invention relates to walking shoes, and particularly to walking shoes with an improved heel portion.

B. Conventional technology Unlike jogging, running, etc., when walking, pedestrians wearing shoelaces
When touching the ground, first touch the ground only at the rearmost part of the lower surface of the shoe's heel, that is, with the tip of the toe raised.

More specifically, the heel contacts the ground at the ridge angle formed by the ground plane of the heel and the rearmost side surface of the heel. In other words, they make contact with the minimum linear area.

Therefore, when touching the floor while walking, it was in an extremely unstable state, and there was a risk of falling or slipping.

Conventionally, in an attempt to avoid such risks, proposals have been made to make the contact during contact with the floor not a linear minimum area contact but a surface contact to avoid the risk of falling and slipping.

A conventional proposal to avoid the risk of falling and slipping when touching the ground is to set the ridge angle formed by the rearmost contact surface of the heel part of the shoe and the rearmost side surface of the heel part at an appropriate angle. It is cut diagonally so that it makes surface contact with the ground when touching the ground while walking.

C. Problems that the invention aims to solve If the above-mentioned conventional proposals are implemented, the risk of falling or slipping when touching the floor while walking will certainly be eliminated, but it will not be possible to walk smoothly and naturally, and it will cause fatigue. There was no way to minimize this, and the drawback was that it was easy to get tired and could damage the ankles and knees.

The present invention attempts to eliminate the above-mentioned drawbacks of walking shoes that have been proposed in the past.

D. Means for Solving the Problems As shown in the drawings, the walking shoe of the present invention has an inclined surface 1 extending forward and an inclined surface 2 extending backward, and the inclined surfaces 1 and 2 are arranged along the center line. 3
The center 6 of the lower end of the inclined surface 1 is located 30 to 35% of the total length from the rear end 7, and the inclined surface The lower end center 8 of 2 is located 8 to 13% of the total length from the rear end 7, and has an outsole 12 consisting of a heel part 10 with a pitch 9 of 8 to 30 mm and a tread part 11. It is characterized by:

E. Actions and Effects The center line of the sole of the foot, from the heel touch floor, heel landing, foot landing, and toe kick-off, is tilted 6 to 12 degrees clockwise with respect to the line indicating the direction of movement. Since walking is performed (so-called cross-legged walking), as in the present invention, the inclined surface 1 extending toward the front and the inclined surface 2 extending toward the rear of the heel portion 10 are aligned with the above-mentioned dynamics of the sole of the foot, and the center line 3 of the shoe By tilting the foot by 6 to 12 degrees in the counterclockwise direction 5 with respect to the perpendicular 4 of the foot, unnatural force is not applied to the foot, tension in the leg muscles is reduced, and walking can be done smoothly with less fatigue.

In addition, in the present invention, the center 8 of the lower end of the inclined surface 2 that spreads backward is located at 8 to 13% of the total length from the rear end 7 of the heel part 10, and is approximately at the position of the calcaneus of the shoe wearer. By matching, it is possible to stably receive the weight when the heel touches the floor, and more reliably prevent falls and slips. At the same time, by positioning the center 6 of the lower end of the forward-spreading slope 1 at 30 to 35% of the total length from the rear end 7 of the heel part 10, the heel part 10 has sufficient space as a ground contact surface, and walking It is possible to secure a sufficient area as a contact surface that can reduce the impact on the unstepped parts of the soles of the feet, such as stone blocks that may occur inside the shoes, allowing for comfortable walking.

Furthermore, walking may be done with short or long strides depending on age, body shape, baggage carried, etc. In this case, the pitch 9 of the heel portion 10 must be taken into consideration. The inventor of the present invention made various changes to Pitch 9 and wore Shoes, and obtained the following findings. If the pitch 9 exceeds 30 mm, the heel and the foot of the foot must strike the ground at the same time while walking, and in such a condition, the knee must be bent while walking, which not only makes walking difficult but also causes damage to the ankle. or hurt your knees. Also, Pitzchi 9
If the distance is less than 8 mm, the foot will not be able to move quickly when kicking off, and the acceleration movement will be small, which is particularly disadvantageous for people with weak Achilles tendons. It is difficult and you will soon feel tired.

Therefore, as in the present invention, the pitch 9 is set to 8 to 30 mm.
By doing so, the rotation of the ankle, which serves as the fulcrum during walking, is carried out effortlessly, and as a result, the ankle, knee, etc. are in a very natural state, and the acceleration movement is carried out smoothly and quickly. You can walk with minimal energy, without causing fatigue, and without damaging your ankles or knees.
