Title: INFLATABLE SHOCK-ABSORBING SOLE STRUCTURE
Abstract:
An inflatable shock-absorbing sole structure, which includes a sole (12) and at least one convex (120) arranged on the sole (12), an airbag room (121) is mounted in the convex (120), and an airbag (21) is arranged in the airbag room (121), the airbag room (121) and the airbag (21) are stretchable and compressible. The shock-absorbing sole structure further includes a built-in air-charging device (43), when the airbag (21) needs to be inflated, the air-charging device (43) can inflate it. The airbag room (121) and the airbag (21) form a shock absorption system in the sole structure, which endows the sole structure a better shock absorption effect. Further, by mounting a built-in air-charging device (43) in the sole structure, when the airbag (21) needs to be inflated, the built-in air-charging device (43) can inflate it. In this way, the air pressure and hardness of the airbag (21) can be adjusted in order to adapt to different road conditions and improve user's wear comfort.
