The present invention provides soles, platforms, or inserts incorporated
into footwear, preferably athletic footwear, designed to promote a more
efficient running technique by an energy-translating sole comprising one
or more angular displacement members, balance-thrust members, and
counterbalance as well as conventional features. Systems and methods of
the present invention promote more efficient running technique by
facilitating foot-strike to occur at a point under and behind the
runner's center of gravity. This may be accomplished, for example, by a
foot-strike member, angular displacement member and balance-thrust member
working cooperatively to displace the runner's center of gravity and
translate gravitational, inertial and ground reaction forces, as well as
muscular tension forces, into linear momentum.
