ABSTRACT:
A ski boot which creates a vacuum between the boot and user's foot, ankle and lower calf. The boot includes a rigid shell formed in sections which permit articulation, and padded liners are mounted within the shell. A flexible sheath secured to the shell forms an hermetical seal about the calf of the user. Means is provided for maintaining a partial vacuum within the boot. The partial vacuum causes both contraction of the boot shell and expansion of the foot to establish a close fit of the foot within the boot. The boot provides lateral stiffness while permitting forward flexing, and the close fit permits the user to achieve precise control during skiing.
