Abstract:
A shoe including a sole having a plurality of recesses with a plurality of discrete compressible shock absorbers initially extending from the recesses beyond a lower surface of the sole until weight is placed upon the shoe by its wearer, the total force required to compress all of the plurality of the shock absorbers to a position flush with the lower surface of the sole being equal to a fraction of the anticipated weight of the wearer sufficient to noticeably reduce discomfort upon impact when walking, the compressible shock absorbers comprising a compressing piece extending beyond the shoe sole with a compression spring being positioned in the recesses above the compressing piece, each recess being large enough to receive the spring and a corresponding retracted compressing piece, the compressing piece being flush with a portion of the sole surrounding the compressing piece when retracted so that the remainder of the wearer's weight is born by the shoe sole.
