PROSTHETIC FOOT SHELL ENABLING RAPID CONVERSION BETWEEN SHOE AND BAREFOOT WALKING

摘要

An easily removable/rapidly replaceable foot shell device for a prosthetic leg, and method for using the device. In a preferred embodiment, a plurality of foot shell devices, often with at least differing heel heights adjusted for barefoot walking, or for use with shoes with different heel heights, will be provided. The devices are designed to allow an average adult to remove a foot shell and replace a foot shell within a short span of time, such as under two minutes. Such a plurality of devices can help a prosthetic leg user avoid prosthetic leg mal-adjustment problems such as hyperextended knee pressure or prosthetic posterior lean. The devices can also adjust the height of the prosthetic foot to compensate for the missing elevation caused by a missing shoe when walking barefoot. The device may be further configured with one or more fasteners to facilitate rapid application and removal.
