Abstract
A shock-absorbing structure includes an elastic helical body, and an elastic helical curved tube. The elastic helical body is formed with a plurality of loops and a plurality of buffer spaces each defined between any two adjacent loops. The elastic helical curved tube is formed with a plurality of curved convex portions each inserted into a respective buffer space and urged between any two adjacent loops. Thus, the buffer spaces of the elastic helical body provide a cushioning effect. In addition, the elastic helical body and the elastic helical curved tube produce an elastic restoring force, so as to damp and reduce the stress applied on the shoe sole, thereby providing a shock-absorbing effect.
