The cushioning performance of the sports shoes refers to the ability of the soles to absorb or reduce shock waves, and is one of the most important performances of the sports shoes. At present, the improvement of the cushioning performance of the sports shoes is mainly started from two aspects of sole materials and sole structures, but the existing research is mainly directed to the whole foot, and the effect is limited. Few researches take the material selection and the structural design in the fore paw region and the heel region as the key points, the cushioning problem is not completely cured, the fore paw region and the heel region are most easily damaged by sports, the pressure in the two regions is effectively dispersed, the design key of the insole of the high-performance cushioning sports shoe is formed, and the development of the insole of the sports shoe with excellent cushioning performance is imperative.
The ostrich lives in desert and wasteland areas, is the biggest biped ratite bird, does not fly, but has extremely strong running capability, can run for 30min at the speed of 60km/h without feeling tired, has the sprint speed of 80km/h, and is a famous and unsufficient racing club. Researches find that the excellent buffering performance of the ostrich foot is mainly attributed to the unique foot structure, the ostrich foot only has two toes (the third toe and the fourth toe), thick foot pads are covered under the two toes, the foot is contacted with the ground to generate huge impact in the high-speed running touchdown process, and the foot pads are pressed and play an important buffering role through the self-deformation characteristic. When the ostrich feet leave the ground, the pressed foot pad is restored to the original shape, and the body tissues are prevented from being damaged by movement.

The paraffin section tissue morphology analysis of the inner layer structure shows that a large amount of elastic fibers and collagen fibers exist, the large dragging effect can be borne, and a large amount of fat cells exist in the inner layer structure, so that the effects of energy storage and buffering are achieved. When the ostrich runs at a high speed, the third toe of the ostrich foot plays a good role in buffering, can effectively weaken the impact on the ground and plays an important role in protecting the skeletal muscle system of the foot. Through ostrich touchdown process numerical simulation, the foot pad buffering mechanism is analyzed, and researches show that the excellent buffering characteristic is derived from the materials, the structures and the mutual assembly relation of the foot pad.
