The present disclosure provides an inflatable shock-absorbing sole structure, which includes a sole and at least one convex arranged on the sole, an airbag room is formed in the convex, and an airbag is arranged in the airbag room, the airbag room and the airbag are stretchable and compressible. The shock-absorbing sole structure further includes a built-in air-charging device, when the airbag needs to be inflated, the air-charging device can inflate it. The present disclosure provides a shock-absorbing sole structure, the airbag room and the airbag 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 in the sole structure, when the air bag needs to be inflated, the built-in air-charging device can inflate it.
