The present embodiment teaches the advantages of the inner midsole of the sports shoe in the following points:

(I) stability and bendability

1. The insole body 1 is provided with the side wall 102, the height of the side wall can enable the foot seat to fall into a deeper depth, the side wall 102 can effectively relieve the unstable situation of the foot after falling to the ground, the stability of the foot in the shoe is improved, the side wall 102 and the base 101 are of an integrally formed structure, the side wall and the base form the insole body 1, and the supporting and blocking effects are better;

2. the holes are formed in the inner and outer side walls 102 of the half sole of the midsole body 1, so that not only is the effect of lateral stability achieved, but also wrinkles generated during forward bending can be effectively reduced, and the feet can be bent more easily and smoothly.

(II) comfortable and shock-absorbing foot feeling

1. As shown in figure 8, in the traditional method for manufacturing the sports shoes, the thick and hard insole cloth 5 and the vamp 4 are sewn and fixed, then are attached to the bottom platform 6, and the insole 7 is placed at the upper end, so that the feedback feeling of the insole material is difficult to directly feel when the insole cloth penetrates. The built-in midsole structure of the embodiment breaks away from the traditional design, as shown in fig. 9, the midsole structure is directly placed in the vamp 4, and the feet can directly feel feedback of the midsole 601, so that the insole is more real-time and more comfortable;

2. in general traditional sports shoes, shock pad 2 most all places the upper strata at insole 601, and built-in insole 601 places shock pad 2 in insole 601 lower floor, except that can reduce the impact that causes the heel foot when falling to the ground, maintains the required shock absorption effect of motion, also can avoid the heel to constantly push down the situation that shock pad 2 and insole body 1 that causes break away from.

As shown in fig. 11, the conventional sole walking pressure is dispersed as follows: 52 +/-7% of the front sole part, 12 +/-5% of the middle part and 33 +/-2% of the heel part; the walking pressure in the built-in midsole of the present embodiment is dispersed as follows: 52 +/-6% of the front sole part, 23 +/-2% of the middle part and 28 +/-4% of the heel part.

(III) support Property

1. The L-shaped supporting block is arranged on the outer side of the half sole, so that the hardness of the outer side of the half sole is improved, the supporting property of the half sole when the half sole falls to the ground is improved, and the condition of sprain caused by inversion is reduced;

2. the middle foot part is designed to be a bulge structure, accords with the position of the human middle foot needing to be supported, can be tightly attached to the foot, and cannot slide (see figure 10). In a reverse view of the design of the traditional insole, the insole 7 is not integrated with the sole, so that after the insole 7 is worn for a long time and the hardness of the insole becomes soft, the sliding probability of the insole 7 is high, the effect of attaching the insole 7 to the foot is poor, and the supporting effect is relatively reduced.

(IV) environmental protection issue

1. The processes and materials are reduced, compared with the sports shoes manufactured by common processes, the shoe insole 7 is omitted, the steps of attaching the insole 601 and the outsole 602 can be reduced, the labor cost is saved, the manufacturing efficiency can be increased, and the material cost can be reduced;

2. the discarding amount of the sneakers is reduced, the long-term property of wearing shoes can be achieved by replacing the built-in midsole 601 in the future, the number of discarded shoes is reduced, and the environmental pollution is reduced.

In a word, although the structure of the special built-in midsole is different from that of the traditional sports shoes, the design of the built-in midsole can achieve the feeling of being easy to bend, stable, shock-absorbing and comfortable, and can meet the requirements of common wearing and running.

In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
