Abstract: 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.

Abstract: A covering for a prosthetic leg. The prosthetic leg is nominally adjusted for optimal performance while the user is wearing shoes. The covering is configured to cosmetically resemble skin, and to shield some or all of the prosthetic leg mechanical components from outside view, thus making the prosthetic leg resemble a natural leg. The covering is designed to enable a prosthetic leg wearer to walk without shoes in a manner that makes it look as if the wearer is walking barefoot. To avoid prosthetic leg misadjustment problems such as hyperextended knee or prosthetic posterior lean, the covering is further configured with one or more internal inserts designed to adjust the height of the prosthetic foot to compensate for the missing elevation caused by the missing shoe. The device may be further configured with one or more fasteners to facilitate rapid application and removal.
