Boot binding interface system

A telemark ski boot system comprising:

• a shell shaped to substantially enclose an internal region corresponding to the shape of a human foot, wherein the shell includes an interior and exterior surface, and wherein the interior surface includes a footbed within the internal region, and wherein the shell includes a metatarsal region corresponding to the lengthwise region at which the metatarsal bones of an enclosed human foot are disposed, and wherein the exterior surface includes a shell bottom externally corresponding to the location of the footbed, and wherein the exterior surface further includes an upper pivot region opposite the shell bottom and configured to enable a heel region of the shell to pivot about the metatarsal region;
• a sole coupled to the shell bottom;
• a binding interface system coupled to the shell bottom at a lengthwise location corresponding to the metatarsal region, wherein binding interface system is contained within the three dimensional space of the shell and sole, and wherein the binding interface system includes a shell coupling system and a binding rotational coupling system;
• wherein the shell coupling system comprises:
• a shell plate disposed on the footbed of the shell;
• a cleat elevationally disposed below the shell bottom, wherein the cleat is fixably disposed relative to the metatarsal region;
• a plurality of couplers extending through the cleat, the shell, and the shell plate;
• and
• wherein the binding rotational coupling system comprises two rotational couplers disposed on the cleat so as to be directly externally laterally accessible in relation to the shell and sole.

• a sole coupled to the shell bottom having a bottom sole surface, wherein the bottom sole surface is the lowest elevational surface of the telemark ski boot system when oriented in an upright configuration corresponding to an upright anatomical human oriented leg and foot, and wherein the bottom sole surface includes a footprint corresponding to the two dimensional perimeter of the bottom sole surface;
• and
• wherein the shell includes a cleat disposed on the shell bottom at a lengthwise location corresponding to the metatarsal region, wherein the cleat is contained between the footbed and the bottom sole surface, and wherein the cleat is contained within the footprint of the bottom sole surface, wherein the cleat further includes two rotational couplers laterally disposed with respect to the shell.
