ABSTRACT:
A shoe has an artificial tendon system, including an elastic band extending through a passageway in the midsole of the shoe. One end of the elastic band is attached to the midsole within the passageway near the forefoot area and the other end is attached near the heel area of the shoe. When the shoe is used, extension of the elastic band stores energy during heelstrike and early propulsion and releases energy during toeoff.
