There are many classification methods for shoes according to wearing objects, manufacturing processes, uses, etc. Among them, sports shoes refer to shoes worn by people when doing sports, and the broad concepts thereof are specifically: proper sports, body-building sports, leisure sports, recreational sports and professional athletic sports.
When a pair of high performance athletic shoes is worn, the support provided to the human body, rebound, and stability during wear are largely dependent on the sole of the shoe. The sole structure of most athletic shoes is largely divided into: an outsole (or outsole, also known as ground-contacting layer) for contacting the ground and primarily providing wear-resistance, and a midsole between the outsole and the insole. In order to pursue high performance athletic shoes, it is desirable that the sole not be too hard nor too soft, and that there be adequate support protection and rapid energy feedback. Too hard soles tend to cause uncomfortable feeling of the soles against the foot when worn, while if too soft soles, wearing comfort is good, but the shock absorption of soles is poor due to too soft soles, and the supporting force provided for the human body is insufficient, so that the wearer can easily sprain the foot, and the supporting force is difficult to provide when walking or running for a long time. If the rebound of the sole is insufficient, the energy consumption of the wearer for a long time is great, and the wearer is easy to feel tired.
It can be seen how to ensure that the sole has both the functions of supporting and damping and rapid rebound, which is an important technical development project. The prior art sole with the functions of supporting, damping and rebound is shown in fig. 1, and is mainly made of polyurethane and wear-resistant rubber. The mold structure design of the sole polyurethane material has the main function of supporting and damping, the side wall is in an elliptical hole shape, and the elliptical hole gradually changes from large to small from the heel to the half sole. In addition, the heel of the sole adopts a hollow structure in the shape of a Chinese character 'men', so that a wearer can rebound by the pressure of movement during movement. However, the sole has reduced rebound while securing support shock absorption, and is not comfortable enough.

Wherein, the outer ring part shown in figure 3 is prepared by adopting a strong and tough polyurethane material.
The inner side of the foot of the outer ring component and the two sides of the outer side of the foot are close to the ground, and are provided with porous structures comprising a plurality of elliptical through holes and a plurality of circular blind holes; a plurality of oval through holes on the outer side of the foot extend from the position close to the heel to the front sole end at intervals, and a plurality of round blind holes extend from the front sole end on the outer side of the foot to the position close to the toe at intervals; the diameters of the plurality of round blind holes are the same, and the long diameters of the plurality of elliptical through holes are gradually reduced to be the diameter of the round blind holes; the porous structures of the inner side and the outer side of the foot are the same; the arrangement intervals of the plurality of elliptical through holes and the plurality of circular blind holes on the outer side of the outer ring component foot are the same; the plurality of elliptical through holes are obliquely arranged at the same acute angle relative to the central line of the length direction of the heel.
The tubular lengths of the elliptical through holes are 13 mm-18 mm; the long diameter of the elliptical through hole at the heel of the outer ring part is 24mm, the short diameter is 7.5mm, and the diameter of the circular blind hole at the half sole is 6mm gradually. The outer ring part is characterized in that 9 elliptical through holes are distributed on the outer side of the heel of the outer ring part, and 11 elliptical through holes are distributed on the inner side of the heel. And the outer contour of the tail end of the half sole of the outer ring part is in a shape of a single reversed signature when seen from the length direction of the midsole.
The inner covering member shown in fig. 6 was prepared by using a high-elasticity foam material (EVA composite foam material obtained in example 2 disclosed in chinese patent document No. 201710266640.0).
The inner covering part is of an integral structure with the upper part being wider than the corresponding lower part, and the lower edge line of the side surface of the upper part is wavy; the inner cover member is in contact with the outer ring member from the upper side surface to the upper bottom surface. The thickness of the half sole stress point of the inner covering part is 14mm, and the thickness of the heel stress point is 23mm. The thickness of the inner covering part at the center of the upper half sole is 12mm, and the thickness of the inner covering part at the center of the upper heel is 15mm.
The ground rubber layer shown in fig. 10 is prepared by adopting a wear-resistant rubber material. The outsole includes: a first wear-resistant rubber layer attached to the outer ring member and a second wear-resistant rubber layer attached to the lower portion of the inner cover member; see fig. 11 for a ground design.
The sole of the sports shoe was used in combination with a conventional upper member and the like to construct a sports shoe, as shown in fig. 12, with a TPU hardness of 70 ° a and a shoe weight of 305.5g. The performance test results of the finished shoe include: the damping G value of the damping performance of the sole is 10.6 (grade 5); the rebound resilience of the sole is 56.1 percent (grade 5). The detection basis comprises: damping performance G value-J4004; rebound-J4004.
In contrast to the sports shoe with sole shown in fig. 1, the shock absorption G value was 11.6 (4-level) and the rebound rate was 49.8% (4-level), but the wearing experience was very poor, and particularly, both sides of the sole were very hard and the comfort was insufficient.
Example 2
According to example 1, a construction sports shoe was produced; except that the TPU had a hardness of 85℃A and a shoe weight of 307.2g. The performance test results of the finished shoe include: the damping G value of the damping performance of the sole is 11.1 (grade 4), and the rebound resilience of the sole is 52.4 (grade 4). The detection was according to example 1.
