Abstract:
1. A method of enabling footwear to store a substantial portion of energy from a human runner's heel landing, for release during a later toe-off comprising: providing a shoe sole member having a support surface, providing a ground contact member having a lower surface, providing a shin brace member operably coupled between said shoe sole member and the runner's lower leg; said shin brace member coupling to said shoe sole member being pivotal, with pivot axis substantially transverse and located substantially adjacent an ankle joint of said runner; providing a motion control apparatus operably coupled between said ground contact member, said shoe sole member, and said shin brace member, said motion control apparatus having a first magnitude of substantially linear travel and at least one second magnitude of resilient urging; wherein the combination of said first magnitude and said second magnitude is configured to a weight of said runner so as to result in at least one predetermined vibratory sub-period or time interval of said resilient urging, so as to increase a running efficiency and comfort level, said vibratory sub-period substantially corresponding to the entirety of the time between said heel landing and said toe-off, and; constraining said ground contact member to two degrees of freedom; firstly, substantially translation in a direction substantially parallel to a shin of said runner, and secondly, rotation to maintain pitching mode parallelism between said support surface and said lower surface, with said motion control apparatus.
