ABSTRACT:
An athletic shoe (10) has a bottom sole (12) and a removable insole (16). The bottom sole (12) has two cavities (24) and (26) that are accessible from the interior (22) of the shoe. Respectively sized removably mounted cushioning cassettes (30) and (32) are removably mounted in the cavities (24) and (26). Each cassette is resiliently flexible and has spring elements (44) seated therein. Viscous fluid indicators (60) and (80) are also mounted on the shoe to determine the impact stresses and compression fit of the shoe on the foot.
