ABSTRACT:
A combined resilient sole of a shoe comprises a sole body defining a cavity at a heel position thereof. A retaining bracket is mounted within the cavity and a number of blind holes in a surface defining the recess. A number of springs are disposed in the blind holes. A footstock is disposed over the retaining bracket. The footstock has a number of bosses extending from an undersurface thereof so that the springs may be compressed between the retaining bracket and the footstock. In a preferred embodiment, a setting sheet is disposed in the recess, and has a same dimension as that of the surface defining the recess. The setting sheet is disposed in the recess and defines a plurality of holes therein aligning with the blind holes of the recess, through which the springs may extend. In such an embodiment, a layer of sponge is covered on a top periphery of the retaining bracket to provide a resilient effect, the layer of sponge being configured as a frame.
