It is attached to the arm velcro 14 attached to the surface, and in this case, confirm the position where the rear end of the attached toe locking pad 11 is attached to the scale display part 7 and attach it.

So, try wearing the shoes with the toe locking pad 11 attached using the male and female velcro (14, 15), and if it is attached to the position that fits the shape of the wearer's own foot, wear the shoe as it is, and the toe locking pad ( If 11) does not fit the shape of your foot, remove the toe locking pad (11) from the pad insertion groove (4), avoid the previously attached position, and attach it to the scale indicator (7) at the front or rear of the Attach it according to the shape of the foot.

After attaching the toe locking pad 11 suitable for the shape of the wearer's own foot as above, the toe locking pad 11 according to the position to which the toe locking pad 11 is attached as shown in FIG. 6 A predetermined distance (c) may be formed between the rear end of) and the rear inclined surface (6) of the pad insertion groove (4), and the distance (c) is a small width of about 5 mm and the rear inclined surface (6) is formed inclined. And, the gap (c) (31) is formed in a wide surface and the sense is not sensitive, so even if you wear shoes in this state, you cannot feel the discomfort or rejection by the gap (c).

By the way, as in the shoes in which the sole (2) according to the present invention is installed, as in general shoes, (700) is spread over the sole (2), so that the above-mentioned small gap (c) is covered by (700), so that the gap ( c) This will not affect the fit of the shoe.

In this way, by selecting the toe locking pad 11 that fits the shape of your foot, and adjusting the installation position of the toe locking pad 11 back and forth to the position that fits the shape of your foot, insert the toe locking pad 11 that fits your foot perfectly. When walking or running while wearing the installed shoes, the applicant of the present invention can experience the excellent effects expected from the prior invention that has been previously applied and patented.

Since the main part of the present invention relates to the toe locking pad 11, a detailed description of the action relationship occurring from the sole corresponding portion 100 at the rear of the toe locking pad 11 to the heel axle corresponding portion 400 describes the conventional invention. Since it is described in the patent publication (10-1898076), it is omitted, and only the part where the toe locking pad 11 is installed will be described in detail with respect to the working relationship.

The toe locking pad 11 as above is formed with a propelling force enhancing part 300 having a convex upper surface, and the concave part 30 corresponding to this propelling force enhancing part 300 is a position where the toe is bent, and the toe 20 and (31) It is located concave between the front, and the driving force enhancing part 300 is inserted into the concave part 30 to be caught.

In addition, the propulsion force enhancement unit 300 has a lower portion corresponding to the concave portion on the big toe side according to the shape of the concave portions 30 of the wearer, and is formed to gradually increase toward the portion corresponding to the concave portion on the small toe side. In addition, the area corresponding to the concave portion on the big toe side is narrow in the anteroposterior direction, and gradually widens toward the portion corresponding to the concave portion on the small toe side, so that the concave portion on the small toe side of the wearer is all increased. Will be in close contact with.

In this state, the toe 20 in front of the concave portion 30 can be bent downward, so that the inclined portion grabs the propulsion enhancing portion 300 like the front and rear ridges of the concave portion, and the little toe side Although the thickness is thin and the support power is weaker than the big toe, the propulsion enhancement part 300 corresponding to the little toe side is wide and high to compensate for the weak support of the little toe.

When moving forward while walking or running in such a state, all of the concave portions on the big toe side to the small toe side are caught by the propulsion force enhancement unit 300 and do not slide backward, so that the propulsion force is not lost, and the propulsion force goes forward as it is. It is augmented, it is possible to increase the walking and running speed by that amount, and it is possible to reduce the physical consumption of the wearer.

In addition, all the bottom surfaces from the big toe to the little toe are in close contact with the toe corresponding part 200 which is obliquely lowered in front of the thrust enhancing part 300, and the thrust enhancing part 300 protruding upward is in close contact with the big toe side. Since it is inserted and caught in all from the concave part 30 to the concave part of the little toe side, the little toe is in close contact with the toe correspondence part 200 even when a strong force is applied toward the little toe depending on the conditions of the ground or walking and driving. In addition, since the concave portion on the little toe side is inserted and hung in the propulsion enhancing unit 300, the wearer does not lose balance and fall, or injure the little toe or ankle.

In addition, as the concave part 30 is hung in the propulsion enhancing part 300, it is possible to prevent the toenail injury of the shoe wearer by preventing the foot from being tilted forward even when going down an inclined road or when it stops momentarily while running or walking. do.

Conversely, when going up an inclined path, the force of the foot slipping down within the shoe tries to act, but in this case, the toe in front of the concave portion 30 in the toe counter 200 inclined downward to the propulsion enhancing portion 300 This will prevent the foot from sliding backwards.

In this way, as the concave part 30 is caught in the propulsion enhancing part 300, it is helpful for the momentary forward driving and the motion to stop while sprinting, thereby helping the agile action. It becomes.
