[0033] like Figures 1 to 4 As shown, the present application provides a shock-absorbing sole that advances layer by layer, which includes a midsole structure 1 and a large bottom sheet 2. The midsole structure 1 includes a heel portion 11, a palm portion 12 and a midsole sheet 13, and the heel portion 11, the palm portion 12 and the midsole sheet 13 are stacked in sequence from bottom to top; the palm portion 12 and the midsole sheet 13 cover the sole of the foot, and the heel portion 11 extends from the heel to the middle of the foot; the rebound rates of the heel portion 11, the palm portion 12 and the midsole sheet 13 increase in sequence; the heel portion 11 and the palm portion 12 are arranged on the large bottom sheet 2, and an anti-slip structure 3 is arranged on the side of the large bottom sheet 2 away from the midsole structure 1.

[0034] A three-layer midsole structure 1 is adopted, and the rebound rates of the heel 11, the palm 12 and the midsole sheet 13 are increased successively, so that the heel 11 has a shock-absorbing effect while improving the stability of the heel 11. The palm 12 has a rebound rate between the heel 11 and the midsole sheet 13, providing force conduction and transition, and the midsole sheet 13 has the highest rebound rate, further increasing comfort. Therefore, through the above-mentioned midsole structure 1 with progressively advancing shock absorption, the rebound rate of the forefoot and the stability of the heel are increased.

[0035] In some embodiments, the rebound rate of the heel 11 is a, 49%≤a<59%; the rebound rate of the palm 12 is b, 59%≤b<69%; the rebound rate of the midsole 13 is c, 69%≤c<80%; in order to meet the above-mentioned rebound rate requirements, the material of the heel 11 is thermoplastic polyether ester elastomer (TPEE), and the material hardness is e, 45°≤e≤55°; the material of the palm 12 is thermoplastic polyether ester elastomer (TPEE), and the material hardness is f, 40°≤f≤50°; the material of the midsole 13 is nylon elastomer (PEBAX), and the material hardness is g, 30°≤g≤40°.

[0036] like Figure 2 As shown, in some embodiments, the length of the heel portion 11 along the medial arch is greater than the length of the heel portion 11 along the lateral arch, which is more in line with ergonomics, has better torsion resistance, and further improves its stability and safety.

[0037] like Figure 2 As shown, in some embodiments, the heel portion 11 includes a base 111 and a first surrounding edge 112. The height of the base 111 gradually decreases from the heel to the midfoot to adapt to human body functional science. The first surrounding edge 112 is arranged around the edge of the base 111. The first surrounding edge 112 and the base 111 are integrally formed, thereby increasing the size of the heel portion 11, further providing support for the heel, and improving its stability. Accordingly, for better assembly, a recessed portion is provided in the area of ​​the palm portion 12 corresponding to the heel portion 11, and the heel portion 11 fits in the above-mentioned recessed portion to ensure that the two are assembled and fit stably.

[0038] In some embodiments, the thickness of the palm portion 12 is greater than 20 mm. By increasing the thickness of the palm portion 12 to further improve the cushioning capacity, it can be prevented from being too thin, and the impact of outdoor hard particles on the foot can be reduced. At the same time, combined with the high rebound rate of the palm portion 12, it can also reduce the impact of the downward pressure on the foot and joints during high-intensity landing, thereby minimizing the possibility of injury.

[0039] like Figure 2As shown, in some embodiments, a second edge 14 is provided on the side of the palm portion 12 away from the heel portion 11 , and the second edge 14 is integrally formed with the palm portion 12 . The second edge 14 is provided around the palm portion 12 to provide support and protection from the lateral direction, thereby further improving stability.

[0040] Furthermore, in the current embodiment, the difference in forefoot and rearfoot drop of the sole with progressively advancing shock absorption is 7.5mm-8.5mm, thereby taking into account both hiking and running functions. The difference in forefoot and rearfoot drop is a term in the prior art, which is the difference between the heel height and the forefoot height, also called offset or heel difference, which will not be elaborated herein.

[0041] like Figure 4 As shown, in some embodiments, the anti-skid structure 3 of the large bottom sheet 2 is a plurality of protrusions arranged on the large bottom sheet 2, and the protrusions are integrally formed with the large bottom sheet 2. Exemplarily, the large bottom sheet 2 is made of rubber material. Specifically, with the direction from the heel to the forefoot as the forward reference, the protrusions include a first protrusion 31, wherein the first protrusion 31 is arranged on the left and right sides of the large bottom sheet 2, and a plurality of first protrusions 31 are arranged at intervals, so that by arranging the first protrusions 31, it has a stronger support performance, ensuring a stronger stability during exercise; the protrusions also include a second protrusion 32, the second protrusion 32 is arranged at the front end of the forefoot area and the rear end of the heel area, and the second protrusion 32 is provided with a plurality of stripes, so that through the second protrusion 32, it can have a stronger grip and anti-skid effect during climbing and descending. Furthermore, the protrusions also include a third protrusion 33, which is arranged in the forefoot area and the heel area and between the first protrusions 31 on both sides. The third protrusion 33 is a pentagonal shape, and the third protrusion 33 located at the tip of the pentagon also has a conformal stripe. The third protrusion 33 located in the forefoot area and the third protrusion 33 located in the heel area are in opposite directions, and can also have stronger grip and anti-slip effect during climbing and descending.
