Combine fig. 1 to fig. 2, according to the utility model discloses a sole 2, sole 2 extends along the fore-and-aft direction, the bottom surface left side of sole 2 is equipped with first rib 21, first rib 21 extends to the rear end of sole 2 along the left side of sole 2 from the front end of sole 2, the bottom surface right side of sole 2 is equipped with second rib 22, second rib 22 extends to the rear end of sole 2 along the right side of sole 2 along the front end of sole 2, the bottom surface of the latter half of sole 2 is equipped with sunk structure 20 in order to construct the elasticity gasbag, sunk structure 20 is located between first rib 21 and the second rib 22.

Specifically, first rib 21 and second rib 22 set up in the left and right sides of sole 2, can play the supporting role, improve the equilibrium of sole 2, improve structural stability. When sole 2 and ground contact, be located the direct and bottom surface contact of first rib 21 and the second rib 22 of sole 2 both sides, can play certain shock attenuation effect, avoid ground to the direct sole 2 face of arriving of the reaction force of foot and produce the impact to the foot, play the cushioning effect. In addition, the area of the sole 2 directly contacting with the ground can be reduced by arranging the first ribs 21 and the second ribs 22, so that the friction resistance is reduced, and the effect of saving labor is achieved.

Furthermore, in the rear half part of the sole 2, a concave structure 20 is arranged on the bottom surface between the first rib 21 and the second rib 22 to construct an elastic air bag, that is, the elastic air bag is arranged in the area corresponding to the heel, when the foot is stepped downwards, the elastic air bag has certain elasticity, so that when the heel exerts force to the rear half part of the sole 2, the elastic air bag can absorb a part of energy; the elastic air bag is constructed into the concave structure 20, and the elastic air bag can form an arch structure in the upper and lower directions of the sole 2, so that the structural strength of the rear half part of the sole 2 can be improved, and the heel support effect can be realized.

According to the sole 2 provided by the embodiment of the utility model, the first ribs 21 and the second ribs 22 are arranged on the sole 2, so that the damping effect and the supporting effect can be achieved on the front half part of the sole 2 and on the two sides of the sole 2, and the stability and the comfort of the sole 2 are improved; set up the elasticity gasbag through the back half at sole 2, can play the absorbed energy, play the effect of buffer protection to the foot, improve sole 2's shock attenuation effect, promote the comfort level when wearing.

In other words, the raised height of the region of the inner surface of the sole 2 opposite the recessed structure 20 with respect to the inner surface of the sole 2 is zero, not more than 20 mm or not more than the recessed depth of said recessed structure 20.

Alternatively, the recessed structure 20 is configured to have a shape that gradually increases in area from top to bottom, which may enhance the cushioning ability and may also increase the structural strength of the recessed structure 20, thereby improving the durability of the sole 2. Alternatively, the concave structures 20 may be provided in a shape equal in area from top to bottom, or the like.

Further, the sidewall of the recess structure 20 is configured to have a multi-step shape, when the force is transmitted downward, the area of the recess structure 20 is gradually enlarged, the step shape of the sidewall of the recess structure 20 can better disperse the impact force to enhance the buffering effect, and the step shape can also improve the aesthetic feeling of the sole 2.
