Detailed Description

In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined below to clearly and completely describe the technical solution of the embodiments of the present invention. It is to be understood that the embodiments described are some, not all embodiments of the invention. Based on the described embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 and 2, a first embodiment of the present invention provides a shoe sole 900. The sole 900 is divided into three regions according to the predetermined partition rule, which are a forefoot region 100, a midfoot region 200 and a heel region 300. The preset partition rule is the length proportion relation among the forefoot area 100, the middle foot area 200 and the heel area 300. In the present embodiment, the length ratio relationship among the forefoot region 100, the midfoot region 200 and the heel region 300 is 4:1: 3. The forefoot region 100 has five forefoot through holes 110 from the medial side 901 to the lateral side 902 of the sole 900. The heel region 300 is provided with three heel through holes from the medial side 901 to the lateral side 902 of the sole 900. The apertures of five forefoot through holes 110 are uniform from medial side 901 to lateral side 902 of sole 900. The hindfoot through hole has a smaller aperture at the medial side 901 than the lateral side 902 of the sole 900. Both forefoot and rearfoot apertures 110, 110 may improve the cushioning properties of sole 900. The arrangement of the heel hole at the medial side 901 of the sole 900 having a smaller aperture than the lateral side 902 allows for better cushioning at the lateral side of the heel area 300 than at the medial side. The different through holes are arranged in the front and rear areas of the sole 900 according to the different pressures applied to the areas of the sole 900 when the user wears and steps on the sole. Since the forefoot region 100 and the heel region 300 are under a greater pressure, the length ratio of the sole 900 is 4:1:3, so that more through holes can be disposed in the entire sole 900, thereby improving the overall cushioning performance of the sole 900.

Referring to FIGS. 1-3, five forefoot through holes 110 are parallel to each other. The aperture of the five forefoot through holes 110 ranges from 2.5 mm to 6 mm. The five front leg through holes 110 include a first front leg through hole 111, a second front leg through hole 112, a third front leg through hole 113, a fourth front leg through hole 114, and a fifth front leg through hole 115. The inner diameters of the five forefoot through holes 110 are sequentially increased from the front side 903 to the rear side 904 of the sole 900, so that the cushioning performance of the forefoot area 100 from the front side 903 to the rear side 904 of the sole 900 is gradually increased, the cushioning requirement that the size of the user's forefoot from the front side 903 to the rear side 904 of the sole 900 is gradually increased is met, and the wearing comfort of the user's forefoot is improved.

Referring to fig. 1, 4 and 5, the rear heel area 300 is provided with a first rear foot through hole 310, a second rear foot through hole 320 and a third rear foot through hole 330. First rearfoot through hole 310 includes a first rearfoot hole central axis L1 from medial side 901 to lateral side 902 of sole 900. The second hindfoot through hole 320 includes a second hindfoot hole central axis L2 from the medial side 901 to the lateral side 902 of the sole 900. Third hindfoot through hole 330 includes a third hindfoot hole medial axis L3 from medial side 901 to lateral side 902 of sole 900. The first rear hole center axis L1, the second rear hole center axis L2, and the third rear hole center axis L3 are arranged in parallel to each other. At the same longitudinal position, the aperture of the second back leg through hole 320 is larger than the apertures of the first back leg through hole 310 and the third back leg through hole 330, so as to better provide a motion buffer for the user. In the present embodiment, the ratio of the lengths of the forefoot region 100, the midfoot region 200 and the heel region 300 is 4:1:3, and the length of the heel region 300 is greater than that of the midfoot region 200. Three heel through holes are arranged in the heel area 300 to improve the cushioning effect of the heel area 300, so that the cushioning requirements of walking or running users on the sole 900 are met. With further reference to fig. 6, in another embodiment, the length ratio between the forefoot region 100, the midfoot region 200 and the heel region 300 is 4:2: 2. The length proportion of heel area 300 is unanimous with middle sole area 200, sets up 2 back foot through holes in heel area 300. The 4:2:2 ratio of this embodiment may provide a relatively greater stiffness to the sole than the 4:1:3 ratio of the previous embodiment, thereby accommodating the supporting force requirements of a user with strenuous exercise on sole 900. In further embodiments, the rear heel area 300 may also be provided with one rear foot through hole or four rear foot through holes or more.

Referring to fig. 5, rear heel region 300 includes a heel inner region 301 and a heel outer region 302.
