Claim Text:
1. A release binding assembly for securing the heel portion of a ski boot to a ski, the release binding assembly comprising: a) a heel pad having a top surface for supporting the ski boot; b) a lower heel assembly adapted to be attached to the ski adjacent to said heel pad, the lower heel assembly comprising: c) a heel track; and d) a lower heel housing having a central longitudinal axis adapted to slidingly engage with said heel track and comprising at least one laterally off-centered spring bias relative to said central longitudinal axis, the laterally off-centered spring bias being applied by a longitudinal pressure spring; e) an upper heel assembly coupled with the lower heel assembly; wherein the lower heel housing and heel track comprise surfaces that asymmetrically refract forces of friction and asymmetrically transpose vectors in a way that reduces the leverage arising from the off-centered longitudinal pressure spring to supply minimally-friction-dissipated longitudinal pressure forces to the boot that act between a toe piece and the heel unit during flex and counter-flex of the ski.
