The present invention relates to a telemark ski boot system configured to enable efficient releasable rotatable coupling to a ski binding at a pivot location corresponding to the metatarsal region. One embodiment of the present invention related to a telemark ski boot system including a shell, a sole, and a binding interface system. The sole is coupled anatomically below the shell and includes a bottom sole surface defining the bottom most portion of the boot. The binding interface system is contained between the shell and bottom of the bottom sole surface and horizontally below the metatarsal region of the boot. In addition, the binding interface system is contained within the two dimensional footprint of the boot. Alternatively or in addition, the binding interface system is contained within the three dimensional space of the shell and sole. The binding interface system may be a rigid cleat.
