Abstract
A sole and viscoelastic sole insert for footwear having an insert filled with an alternating configuration of gel and gas filled cells is provided. The impact response can be varied by altering the ratio of gas-filled to gel-filled cells or by altering the pressure under which the cells and/or pellets are filled with gas or gel. In similar fashion, an insert incorporating one or more springs may provide a number of impact responses by varying the number of springs and/or the spring design parameters. Advantageously, the inserts can be adapted to be readily removable from the sole so that the wearer can change the insert to provide a 'universal' shoe ideally suited for a variety of applications and wearer preferences.
