Abstract

An exemplary ski boot as described herein includes an outer shell, at least one guide member, a tensioning mechanism, and a tension member that is operably coupled with the tensioning mechanism so that an operation of the tensioning mechanism adjusts a tension of the tension member. The tensioning mechanism and the at least one guide member are coupled with the outer shell and the at least one guide member is operably coupled with the tension member to route or direct the tension member along a lace path about the ski boot's outer shell. The lace path includes an upper end, a lower end, and a midpoint positioned between the upper end and lower end. The tensioning mechanism is positioned near the midpoint of the lace path.
