Improved structure of sole of marathon shoe

Abstract

The invention discloses an improved structure of a sole of a marathon shoe. On the basis of a wearing state, the grounding surface of the arch part of the soft sole is fixedly provided with at least one hard strip-shaped reinforcing rib along the length direction of the sole. According to the invention, the strength of the arch part of the sole can be enhanced, and the sole can be prevented from being twisted in a wearing motion process; the weight of the sole is greatly reduced by the structure; and the strength of the arch part of the sole is ensured at the same time, and force transmission of the sole is facilitated, so that a marathoner saves more labor when running, and is faster and easier, and the competition results are also effectively improved.

Description

Technical field [0001] The invention relates to a sole structure of sports shoes, in particular to an improved structure of the sole of marathon shoes. Background technique [0002] In order to avoid distortion of the arch part of the ordinary marathon shoes, the following measures are taken: the arch of the sole and the ground of the heel part are made into a thick layer to improve the overall strength, and the arch part of the ground is made on the ground It is a structure that is recessed toward the inside of the shoe. This structure prevents the arch of the foot from being deformed. However, this structure will cause the sole weight to be large, and the transition between the arch of the foot and the forefoot is sudden, and the force transmission performance is poor, which increases the athlete's work. It is easy to cause fatigue to athletes, which is not conducive to long-distance and long-distance sports of marathon athletes. Summary of the invention [0003] In order to ov...

Problems solved by technology

[0002] The soles of ordinary marathon shoes take the following measures to prevent the arch of the foot from twisting: the arch of the sole and the ground of the heel part are made into a thickened layer to improve the overall strength, and the ground of the arch of the foot is made This structure is used to prevent the arch of the foot from twisting and deforming. However, this structure will cause the sole to be heavy, and the transition between the arch of the foot and the forefoot will be sudden, and the force transmission performance will be poor, which will increase the work of the athlete. It is easy to make athletes feel fatigued, which is not conducive to long-term and long-distance sports for marathon athletes
