[0030] The present application is further described in detail below with reference to the accompanying drawings.

[0031] The present application discloses an elastic, flexible, and non-slip sole. Figure 1 , including a sole upper layer 1, an elastic layer 2 and a non-slip bottom layer 3; the sole upper layer 1 is composed of a natural rubber layer and a TPU layer. The toughness and softness of the sole are comprehensively improved through the compounding of natural rubber and TPU.

The forefoot portion 21 is provided with several connected shock-absorbing blocks 211, and the heel portion 22 is provided with a double-layer buffer block 221. The arrangement of the shock-absorbing blocks 211 and the buffer blocks 221 improves the elastic performance of the sole. At the same time, the buffer block 221 of the heel portion 22 is double-layered, which effectively improves the support strength of the heel portion 22 with greater bearing capacity, obtains good elasticity while maintaining a good support effect, and improves the wearing comfort of the sole.

[0033] Reference Figure 1 、 3 The side walls of the double-layer buffer blocks 221 are connected in sequence, and connecting blocks 7 are fixed between the buffer blocks 221. The connecting blocks 7 are diamond-shaped, and the connecting blocks 7 are arranged in the middle of the buffer blocks 221 adjacent to each other in the upper, lower, left and right directions. The side walls of the buffer blocks 221 form an inclined surface that matches the shape of the connecting blocks 7; the diamond-shaped connecting blocks 7 match the shapes of the buffer blocks 221, which, on the one hand, improves the connection firmness of the adjacent buffer blocks 221, and on the other hand, improves the supporting effect.

[0034] Reference Figure 1 、 4 The elastic layer 2 is fixed between the sole upper layer 1 and the anti-skid bottom layer 3 by the fixing structure 4; the fixing structure 4 includes fixing rods 41 respectively arranged opposite to each other at the rear end of the elastic layer 2, and the relative fixing rods 41 correspond to the sole upper layer 1 and the anti-skid bottom layer 3 respectively and can move back to each other. A clamping block 5 is formed on the side wall of the fixing rod 41. When the fixing rod 41 is inserted into the corresponding sole upper layer 1 and the anti-skid bottom layer 3, the clamping block 5 can be respectively clamped to the corresponding sole upper layer 1 and the anti-skid bottom layer 3; through the insertion of the fixing rod 41 and the clamping of the clamping block 5 in the sole upper layer 1 and the anti-skid bottom layer 3 respectively, the front ends of the sole upper layer 1, the elastic layer 2 and the anti-skid bottom layer 3 are bonded and fixed, so that the connection between the sole upper layer 1, the elastic layer 2 and the anti-skid bottom layer 3 is more stable.

[0035] Reference Figure 1 、 4 The fixing structure 4 also includes a pushing block 42, which is arranged at both ends of the elastic layer 2 and respectively located between the opposite fixing rods 41. One end of the pushing block 42 is passed through the outer wall of the elastic layer 2, and the end of the pushing block 42 located outside the elastic layer 2 is in an arc shape that matches the outer wall of the elastic layer 2; the other end of the pushing block 42 close to the fixing rod 41 is conical, and the pushing block 42 is pushed inward from the outside of the elastic layer 2, driving the relative fixing rods 41 to move back to back and respectively insert into the corresponding sole upper layer 1 and anti-slip bottom layer 3, thereby completing the fixation between the sole upper layer 1, the elastic layer 2 and the anti-slip bottom layer 3.

[0036] Reference Figure 1 、 4 A protrusion 6 is formed on the side wall of the push block 42, which is interference fit with the elastic layer 2; the push block 42 is fixed in the elastic layer 2 by the protrusion 6 on the side wall of the push block 42, so that the fixing rod 41 can achieve connection stability in the corresponding sole upper layer 1 and anti-slip bottom layer 3.
