Move, so as to achieve the convenience of walking, make the muscles of the lower body of the walker developed, increase the amount of exercise and improve endurance, power and agility.

Front bottom among the present invention, rear bottom refers to, when taking the position of upward slope as interface, the bottom of the forefoot position of the interface is the front bottom (OFL), and the bottom of the heel position is the back bottom (OBL). The above-mentioned forefoot part refers to the part where the toes are located, and the heel part is the part where the heel is located.

On the drawings attached in the present invention, for convenience, the forefoot and the heel are specifically marked with the insole as the center, and the same is true for the outsole, where the respective corresponding positions are the forefoot and the heel.

In the present invention, the toes of the body refer to the soles of the feet corresponding to the phalanges, the palms of the body refer to the soles of the feet corresponding to the middle foot bones, and the rear heels of the body refer to the soles of the feet corresponding to the heel bones. The forefoot part refers to the upper part of the sole where the toe part rests, the slope part refers to the upper part of the sole where the palm rests, and the heel part refers to the upper part of the sole where the heel part rests.

The following is a description of the structure of the functional shoes of the present invention using the drawings.

The appended drawings focus on illustrating the constituent elements related to the present invention, and the elements commonly understood by professionals are not marked one by one. In particular, the size ratio of the constituent elements is different in the diagram, but such a difference in the drawing is easily understood by professionals, so it is also deleted.

In the present invention, Fig. 3 is a side view illustrating the technical idea of functional shoes in the present invention, Fig. 4 is a cross-sectional view of the outer sole and inner sole of functional shoes, and Fig. 5 is a perspective view of the inner sole of the present invention.

The functional shoes in the present invention are composed of sole and carapace; the sole is composed of the bottom surface that gets along with the ground when the wearer walks and the top that gets along with the wearer's instep, and the carapace is connected with the sole to wrap the toes, heel and instep of the wearer , Ankle. The outer sole and the inner sole of the above shoe sole are characterized in that the front sole of the forefoot portion is inclined upward in the longitudinal direction.

Therefore, the rear soles of the above-mentioned functional shoes are formed parallel to the bottom surface, and can be stably landed on the ground compared with the conventional Masai shoes. When walking on slopes or going up and down stairs, you can walk stably without feeling inconvenient. When walking on flat ground, you don’t need to apply force to your legs, and the weight will naturally transfer due to the inclination angle, making walking convenient.

According to the appended drawings, the structure of the outsole in the above invention will be described in detail.

The structure of the outer bottom 10 in the present invention is to form a linear slope in the length direction from the back bottom to the front bottom, and the slope is formed in the ratio of the length of the back bottom (OBL) to the length of the front bottom (OFL). Where 53-56 is compared to 44-47, the inclination angle (α) of the inclined part is 13-17°, and the inclined part is formed by the entire length of the front bottom (OFL).

The forming point and the size of the angle of the above-mentioned inclination are designed according to ergonomics. If the inclination is formed before the above-mentioned limited range or the inclination angle is smaller than the above range, when walking, the body can be kept stable, but due to the elastic force Discomfort in the function causes the thighs to work hard; if the inclination is formed behind the above range or the inclination angle is greater than the above range, the inclination angle of the front bottom is too large, which leads to the movement before walking, which also makes the legs strenuous. Not only that, but also the body The ground is also unstable, and the walker will get tired easily.

According to the attached drawings, the structure of the inner bottom among the above inventions will be described in detail.

The insole 20 in the present invention is improved from the structure of the insole of the functional shoe described in Korean Patent No. 10-533595, and is configured so that the wearer feels the least fatigue according to ergonomics.

The insole 20 among the present invention is configured to form an upward slope approximately straight from the heel 23 to the forefoot 21 in the length direction, and the ratio of the length of the forefoot to the total length of the insole should be 0.2 to 0.3 than 1. If the length of the front of the shoe is less than 0.2, the wearer’s toes will get stuck on the slope 22 of the front of the shoe 21 if the length of the front of the shoe is less than 0.2. , leading to a decrease in the sense of wearing.

The structure of the inner sole 20 is a nearly linear upwardly inclined structure with an inclination angle (β) from the heel portion 23 to the forefoot portion 21 of 2.5° to 4.0°. When walking, it prevents the heel from slipping and makes the toes fall naturally and stably. The inclination angle is an appropriate angle during exercise and walking. Even if you walk or run for a long time, the Achilles tendon will not feel very tired and can be effectively Increase your physical activity.

When the inclination angle (β) of the above-mentioned inclined portion 22 is less than 2.5°, the degree of relaxation of the Achilles tendon will be very small, and the amount of exercise will be very little, which cannot meet the requirements of modern people to effectively increase the amount of exercise; when it is greater than 4.0°, the Achilles tendon will be relaxed. The speed will be large, and the amount of exercise will increase, but it will lead to a decrease in wearing feeling, loss of balance, easy fall, and excessive impact on the Achilles tendon.

In the present invention, the materials used in the above-mentioned outer bottom 10 and inner bottom 20 are usually materials used in the outer bottom and inner bottom of shoes, and are suitable for polyurethane or bottom foamed polyethylene. In addition to the above-mentioned foam, Can be a foam material with the same properties.

Therefore, both the outsole 10 and the insole 20 of the functional shoes with the above-mentioned structure form a structure in which the front part of the shoe is slightly upwardly inclined compared with the heel part, which is set according to ergonomics and can make the body stable and maintain balance when walking. Landing on the ground, the walker does not add force to the legs, and the weight will naturally move due to the inclination angle of the inner bottom, so as to facilitate walking, make the muscles of the walker's lower body developed, increase the amount of exercise and improve endurance, power and agility.

The advantages of the present invention have been described above based on the attached drawings, but this is not limited to the description based on the accompanying drawings, and various substitutions and modifications are possible within the technical idea of the present invention.
