First Claim
Patent Images
1. A sport boot comprising:
- a boot body adapted to cover the ankle of a wearer;
an aperture through both sides of said boot body proximate to the ankle;
one or more pistons connected to said boot body such that said one or more pistons are operable to restrict plantar flexion but not restrict plantar extension; and
a sheath adapted to connect to said boot body and cover said one or more pistons.

Abstract
A sport boot that allows for a reduced resistance plantar extension coupled with a controlled, resistive plantar flexion motion. The preferred embodiments provide a one-piece boot made of a flexible material, such as leather. A triangular portion of the boot material, from a point just posterior to the ankle opening to a larger area anterior of the ankle on both sides of the boot, is cut out. One or more piston assemblies are attached to the boot material on both sides of the cut away portion of the boot. The piston assemblies provide resistance to compression during flexion of the boot but offer no resistance to extension during plantar extension.
