The functionality of the sports shoes is mainly realized by the combination of different materials and structures, and the research of the multi-layer composite sole structure is also an important research direction of the development of the sports shoes. At present, the multilayer composite structure of the sole is mainly divided into: (1) a stacked composite structure of a plurality of functional foam materials; (2) compounding the foaming material with the supporting structure.

However, the existing sole structure still has the following problems: (1) The contact mode of the runner is changed continuously in the second half of the full horse, the contact mode is changed from the contact mode of the forefoot and the midfoot to the contact mode of the heel, and the heel needs to have higher rebound resilience and shock absorption performance when the contact mode of the heel is changed into the contact mode of the midfoot so as to compensate the muscle strength reduction phenomenon caused by the fatigue of the lower limbs and the foot muscles in the second half. (2) The supporting plate of the existing running shoes forms a lever effect more, so that a runner is guided to quickly transition to the forefoot, but the rigidity of the middle layer can be increased by embedding the supporting plate, the lever effect can be reduced to a certain extent by larger deformation of the lower-layer middle-layer bottom material, and the movement mode can be changed due to descending of the arch of the runner in the second half, the abnormal skeleton force line can be caused by the wrong movement mode, and the stress effect is generated in an incorrect position, so that the pain and diseases are caused by worn joints, and the requirement of the long-distance second half on the supportability of the midfoot region is higher. (3) Most of the existing marathon racing running shoes are high in propulsive performance, and the cushioning performance and the supporting performance cannot be well considered and improved, so that the limitation of adaptation crowd is large for marathon runners of different levels.

As shown in fig. 8 and 9, the first elastic layer 1 is provided with two fore-sole grooves and two heel grooves, the two fore-sole grooves are respectively located at the inner side and the outer side of the fore-sole part of the first elastic layer 1, and the two heel grooves are respectively located at the inner side and the outer side of the heel part of the first elastic layer 1. The half sole section 21 of the first support plate 2 includes a half sole concave 24 and half sole convex 25 on both sides, and the half sole convex 25 on both sides and two half sole grooves on the first elastic layer 1 form a half sole inner hollow structure 61 and a half sole outer hollow structure 62 respectively, and the half sole concave 24 is attached to the groove on the half sole portion of the first elastic layer 1. As shown in fig. 10 and 11, a first bump 31 is disposed in the middle of the half sole portion of the second elastic layer 3, the first bump 31 is attached to the half sole concave 24 of the first support plate 2, arched grooves are disposed on two sides of the first bump 31, and the half sole convex 25 on two sides of the half sole section 21 of the first support plate 2 is attached to the grooves on two sides of the first bump 31.

The second bump 32 and the forefoot recess 24 of the first support plate are disposed corresponding to the second and third metatarsals of the human foot.

A plurality of three-dimensional concave-convex structures are formed in the supporting plate and the sole structure, and the concave-convex structures can be elastically deformed, so that energy can be stored or released along with deformation, and a powerful propulsion effect is provided for the foot pedaling stage of a human body.

The upward convex structures formed at the first, fourth and fifth metatarsal regions and the downward concave structures formed at the second and third metatarsal regions of the sole half sole can conform to the force-exerting characteristics of the treading stage of running exercise of a human body, on one hand, the sole can provide supporting and propelling actions for the first, fourth and fifth metatarsal regions, is convenient for better forced treading and stretching, improves the exercise performance, and on the other hand, the sole can better disperse larger stress generated at the second and third metatarsal regions, reduce impact and improve the buffering effect.

The midfoot hollow structure 63 of the midfoot portion of the sole provides a coordinated force feedback mechanism for the overall running exercise process by superimposing the highly elastic midsole material with the embedded support plate, and can recover the energy generated by the wearer during landing each step and re-release the energy during pedaling. Preferably, the second support plate 4 is arranged corresponding to the hollow structure 63 of the midfoot, and the structure of the upper and lower embedded support plates of the midfoot part is more conducive to the rapid rebound of the high-elastic material, so as to restore the original shape of the high-elastic material and further release a large amount of energy.

The heel position of sole through set up thicker high-elastic material in middle part region, provides more excellent buffering shock attenuation effect for the heel, and the structural design of peripheral region can promote the heel stability of human foot clap stage again. In addition, the downwardly sloping heel counter 26 can gradually increase the stiffness from the resting stage to the supporting stage, shortening the transition time.

Preferably, in the sole structure described above, the stiffness of the half sole convex portion 25 located on the inner side of the half sole section of the first support plate is greater than the stiffness of the half sole convex portion 25 located on the outer side of the half sole section, and this can be achieved by adjusting the layering or other means. The pressure of the inner side of the foot half sole is raised to the maximum in the pedaling stage, and the arrangement mode is beneficial to further improving the supporting and pushing effects of the inner side of the half sole.

Further, as shown in fig. 2 and 3, the size of the half-sole inner hollow structure 61 is smaller than that of the half-sole outer hollow structure 62 to enhance the support of the half-sole inner side; and/or the size of medial heel hollow structure 64 is smaller than the size of lateral heel hollow structure 65 to enhance medial heel support. The distance A between the inner half sole hollow structure 61 and the middle foot hollow structure 63 is larger than the distance B between the outer half sole hollow structure 62 and the middle foot hollow structure 63, so that the middle sole material between the inner half sole hollow structures has a larger coverage area; and/or the distance C between the medial heel hollow structure 64 and the midfoot hollow structure 63 is greater than the distance D between the lateral heel hollow structure 65 and the midfoot hollow structure 63 to provide a greater coverage area for the midsole material between the medial heel hollow structures.

The reason for adopting the arrangement mode is that the demand of the supporting property and the deformation resistance of the inner side part close to the heel area is larger than that of the outer side part according to the difference of the force characteristics of the human foot in the process from landing to stepping off. Therefore, the medial hollow structure of the heel portion is smaller in size and larger in midsole material coverage area than the lateral hollow structure, and can provide more adequate support and stability to the medial sole during the pedaling stage.

Further, the size of medial heel hollow structure 64 is greater than the size of medial half-sole hollow structure 61, and the size of lateral heel hollow structure 65 is greater than the size of lateral half-sole hollow structure 62. That is, the hollow structure of the heel portion is larger in size than the hollow structure of the forefoot portion. The heel area is more focused on cushioning function, thus requiring deeper downward curvature to increase deformation space, thereby improving cushioning of the heel portion, and the forefoot portion is more focused on the rapid rebound function of the push-over stage, thus requiring rapid recovery of shape after deformation to provide upward and forward potential energy.

Preferably, the width of the half sole inner hollow structure 61 is 7-11.5mm, preferably 10.9mm, and the maximum height is 2-5.5mm, preferably 3.5mm; the width of the half sole outer hollow structure 62 is 8-13.9mm, preferably 12.5mm, and the maximum height is 2-5.1mm, preferably 3.6mm; the medial heel hollow structure 64 has a width of 11.5-17.9mm, preferably 15.2mm, and a maximum height of 2-7.2mm, preferably 3.9mm; the width of the heel lateral hollow structure 65 is 15-23.6mm, preferably 19.3mm, and the maximum height is 2-5.9mm, preferably 4.2mm.

Preferably, the distance between the forefoot side hollow structure 61 and the midfoot hollow structure 63 is 17.3-24.6mm, preferably 20.9mm, and the distance between the forefoot side hollow structure 62 and the midfoot hollow structure 63 is 13.9-21.6mm, preferably 17.5mm; the distance between medial heel hollow structure 64 and midfoot hollow structure 63 is 17.9-26.8mm, preferably 24.8mm, and the distance between lateral heel hollow structure 65 and midfoot hollow structure 63 is 12.6-20.1mm, preferably 17.3mm.

Further, the outsole 5 provided at the lower portion of the first elastic layer 1 is provided with a pattern 7 on a side facing the ground, and the density of the pattern 7 on the outer side of the heel portion of the outsole 5, the outer side of the midfoot portion, and the inner side of the forefoot portion is greater than the density of the pattern 7 on the inner side of the heel portion of the outsole 5, the inner side of the midfoot portion, and the outer side of the forefoot portion. Preferably, the density of the tread pattern 7 in the forefoot portion of the outsole 5 increases from the outer side to the inner side of the forefoot portion. According to the plantar pressure distribution characteristics of the whole gait cycle from the grounding to the stepping-off of the runner (the grounding stage, the heel or the lateral side of the midfoot grounding, the stepping-extending stage, a certain degree of internal rotation rolling stepping extending from outside to inside, and the medial side stress of the front sole can be larger than that of the lateral side), the arrangement mode is adopted to help increase the contact area of the areas and the ground, and further improve the stability.

1. First, the sports shoe 13c in fig. 13 was subjected to a shoe-finishing performance test, and the test results were as follows:

slip resistance test: dry limited slip 1.05, wet limited slip 0.74 (SATRA 144 horizontal mode), higher than most professional running shoes limited slip parameters (dry mean=1.03, wet mean=0.5) at present, can provide better limited slip effect;

bending stiffness test: 0.67Nm/Deg.

2. Shock absorption test

As shown in fig. 14, the "shock absorbing system" of the generation 2 is the test shoe 13a in fig. 13, the "racing system fly " is the test shoe 13b in fig. 13, and the "3 " is the sports shoe 13c in fig. 13.

Wherein, the two indexes of the first peak value and the time for reaching the first peak value are related to the impact force, the smaller the first peak value is, the better the cushioning property is, the longer the time for reaching the first peak value is, and the better the cushioning property is; the two indexes of the maximum loading rate and the average loading rate are related to knee joint injury, and the smaller the two indexes are, the smaller the injury is.

It was thus found that the sports shoe 13c provided with the shock-absorbing support sole of the present invention is excellent in shock-absorbing performance, contributing to reduction of sports injuries.

3. Stability test

As shown in fig. 15, the "shock absorbing system" of the generation 2 is the test shoe 13a in fig. 13, the "racing system fly " is the test shoe 13b in fig. 13, and the "3 " is the sports shoe 13c in fig. 13.

The two indexes of the maximum ankle eversion speed and the maximum eversion angle are related to heel stability, the two indexes of the maximum dorsiflexion speed of the running shoe in the braking stage and the difference value of the running shoe speed in the braking and supporting stage are related to midfoot transition smoothness and supportability, and in a certain range, the smaller the numerical value is, the better the stability is represented, and the transition smoothness and supportability are the better.

As a result, it was found that the sports shoe 13c provided with the shock-absorbing and supporting sole of the present invention had a heel stability improved by about 7% and a midfoot transition smoothness and supporting performance improved by about 8% as compared with the two comparative test shoes.

4. Propulsion test

As shown in fig. 16, the "shock absorbing system" of the generation 2 is the test shoe 13a in fig. 13, the "racing system fly " is the test shoe 13b in fig. 13, and the "3 " is the sports shoe 13c in fig. 13.

The four indexes of the plantar toe joint bending and stretching movement range, the plantar toe joint peak negative power, the pushing time and the landing time in the pedaling and stretching stage are related to the propulsive performance, and the smaller the numerical value is in a certain range, the better the propulsive performance is represented.

It was thus found that the propulsive performance of the sports shoe 13c provided with the shock-absorbing support sole according to the present invention was significantly improved as compared with both the test sample shoe 13a and the test sample shoe 13b.

5. Exercise injury risk test

As shown in fig. 17, the "shock absorbing system" of the generation 2 is the test shoe 13a in fig. 13, the "racing system fly " is the test shoe 13b in fig. 13, and the "3 " is the sports shoe 13c in fig. 13.

The index "maximum abduction moment of knee joint" is smaller in a certain range, and represents smaller damage risk.

It can thus be seen that the sports shoe 13c provided with the shock-absorbing support sole according to the invention has a risk of injury index that is significantly smaller than that of the

test shoes
