2. The setting range of buffering portion accounts for two-thirds to three-quarters of the upper top surface of sole body, and buffering portion is the platy crossbeam of mutual crisscross, and platy crossbeam is under mutual crisscross natural formation has the air pocket, and buffering portion's effect lies in that it contacts with the shoe-pad, can cooperate with the shoe-pad to promote the travelling comfort of wearing.

3. The first antiskid zone is a W-shaped groove, the second antiskid zone is a V-shaped groove, and the W-shaped structural design and the V-shaped structural design can bring better antiskid performance compared with the conventional straight strip-shaped design.

4. Through be provided with the elastic groove on the week side of sole body, the elastic performance of sole can be strengthened to the elastic groove, and its principle is that the mode through the fluting makes the sole supportability originally slightly decline, makes the sole body become softer.

5. The elastic grooves are strip-shaped grooves, the elastic grooves are arranged on the sole body and located in the heel area, the elastic grooves are parallel to each other, the included angle between the elastic grooves and the horizontal plane is 45-60 degrees, the groove depth is 3-5 mm, when pressure is applied, the elastic grooves retract to absorb the pressure, and the inclined design can enable the elastic grooves to have rebound performance like a spring.
