Description

[Detailed description of the invention] This invention relates to the improvement of shoes for track and field events.The purpose of this invention is to suppress excessive supination movement that occurs in the left foot when running around corners (curved sections) in track events, and to reduce the loss of kicking force. The objective is to provide shoes with less time loss.

Shoes for track and field events, both for track and field events, have spikes on the soles as well as various uneven patterns as anti-slip means, but these are mainly formed on the front ground contact area.

However, track competitions involve stretching and running around corners;
The weight-bearing path for both left and right feet is to receive a landing impact on the outside of the heel, then pass through the outside of the ground contact area, reach the front contact area, move the front contact area inward, and kick off with the inside of the toe area to run. Although it is a thing,
In a corner, the right foot runs along the weight-bearing path described above, but the left foot remains horizontal without being deflected to the outside of the heel, and the entire heel area receives the landing impact.
Next, it passes through the inside of the ground contact area, reaches the front ground contact area, and presents a weight-bearing path that kicks off with the inside of the toe area, and in the path from this landing to the front ground contact area, the heel part undergoes supination movement, and the heel part supinates, moving toward the outside of the corner. You will run around corners while sliding around.

Therefore, it has been found that with the conventional symmetrically constructed sole, the left foot excessively supinates and slides too far to the outside of the corner, resulting in time loss.

Therefore, this invention is intended to improve such drawbacks, and an embodiment thereof will be described with reference to the drawings.

That is, in track and field shoes in which spikes are provided on the front sole 2 of the left and right shoe soles, the distance from the arch of the front sole 2 provided with the spikes of the left shoe to the heel 1
The shoe for track and field, suitable for track, is characterized in that a plurality of protrusions 4 formed integrally with the outsole are provided in the inner area 3 of the outsole up to the area.

Note that the shape of the protrusion is arbitrary, but cylindrical, prismatic, and conical shapes are preferable.

In this invention, as mentioned above, the protrusions 4, 4... are provided only on the sole of the left foot, and therefore, during stretching, the protrusions 4, 4... are provided only on the sole of the left foot, and therefore, during stretching, the protrusions 4, 4... The inner region 3 from 1 to the arch A of the front sole 2 does not impede running due to the protrusion.

In a corner, the inner region 3 from the heel 1 of the left foot to the arch A of the front sole 2 receives a landing impact, and a supination motion occurs in which the heel 1 slides toward the outside of the corner. It turns out.

Therefore, by forming protrusions 4, 4, . Therefore, it is possible to provide a track and field shoe suitable for track, which reduces the loss of kicking force, considerably reduces time loss at corners, and contributes to improving records.

Claims (1)

[Scope of utility model registration request] In track and field shoes that have spikes on the front sole of the left shoe, an arbitrarily shaped shoe that is integrally formed with the outsole is placed on the inside area of the outsole from the arch of the front sole where the spikes are provided to the heel area. Track and field shoes suitable for track, characterized by having a plurality of protrusions.
