Abstract
A keel is provided having a spring portion and a connecting portion. The spring portion can have a split section that is divided into two sections. Each section can have a top open channel formed therein. Each channel is compressible during compression of the keel. A compression member can be placed within each channel to control or limit the amount of keel spring compression. The connecting portion is rigidly connected to a rigid center support. The top of the center support can have a threaded connector, which allows for vertically adjustable connection of an adjacent prosthetic component. A heel is also provided having a spring portion and a connecting portion. The spring portion can have a top open channel formed therein. The channel is compressible during compression of the heel. A compression member can be placed within the channel to control or limit the amount of heel spring compression.
