ABSTRACT:
A cushion cell for shoes includes a casing with an hour-glass-shaped compressible member received therein which is composed of a spiral wire extending in a vertical direction. The compressible member includes an upper portion and a lower portion, the spiral wire of the upper portion can be inserted in a corresponding spiral gap of the lower portion when the cushion cell is compressed. The distance that the compressible member is compressed is much longer than the chambers in a conventional outsole.
