Abstract
A sports boot such as used for skiing has an upper shell interconnected in the ankle region to a lower vamp shell by a pair of side primary pivots.

The receptacles hold a replaceable resilient insert, the vertical extent of which determines the forward lean angle of the upper shell, and the resiliency of which controls the flex characteristics of the upper shell when pivoted relative to the lower shell. The ends of the receptacles form overlapping stop flanges which abut a replaceable bumper having a vertical extent which controls the maximum rear lean angle of the upper.
