  • Midsole for shoe
    Patent number: 5822886
    Abstract: An integrally molded midsole for an athletic shoe having tubular suspension members disclosed. The tubular suspension members behave as springs and have spring constants which may be designed for a particular application by choice of the tube length, the tube wall thickness or the hardness of the tube material. Preferably, the midsole is made of an elastomer such as HYTREL that is cast in a preformed shape and thereafter subjected to substantial compressive forces so that the tubular springs take a compression set and thereafter perform as near-ideal springs.
    Type: Grant

    Date of Patent: October 20, 1998
    Assignee: Adidas International, BV
    Inventors: Simon Luthi, Xavier Kalin, Wolfgang Scholz, Edgar Stussi
