Abstract: A prosthetic device having a rotatable pyramid and lateral travel limit is provided. A first member has a first end connectable to a prosthetic component and a second end with a bar having sides and a distal face. The distal face has ribs thereon. A central hole is provided through the first member. A second member has a first end with a pyramid and a second end with a ring that defines a recess with a solid face. A third member has a dome on a first end and a channel on the second end. The pyramid extends through a central hole through the dome. A screw passes through the central hole of the first member wherein it can engage the second member within the recess. The lateral movement of the bar within the channel is bound by the screw contacting the second member.

Abstract: A keel is provided having a spring portion and a connecting portion. The spring portion can have a channel that is compressible during compression of the keel. A variably adjustable compression member can be provided. The connecting portion is rigidly connected to a rigid center support. 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 variably adjustable compression member can be placed within the channel. Alternatively, heel and keel springs located at least partially external of the heel and keel can be provided. The heel spring can act against either the keel or the center support, and the keel spring can act against either the heel or the center support.
