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 lower edge of the upper shell has an integrally molded front receptacle which faces a front receptacle integrally molded into the upper edge of the lower vamp shell. 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. Rear entry into the boot is provided by a rear door connected by a pair of side door pivots to the upper, and which overlaps a separate replaceable heel door with interior padding for holding down the wearer's heel. When the rear door is swung downwardly, the heel door automatically opens rearwardly. In alternate embodiments, the resilient insert and bumper are augmented by an external piston and sleeve mechanism, and the rear door can be connected by side hinges to the upper.
