Claim 9:
10. A prosthetic foot having an anterior toe end, and a posterior heel end, comprising:
a frame configured to couple to a prosthetic leg,
a forefoot keel member including a first resilient substrate extending from the frame to the anterior toe end of the prosthetic foot, the first resilient substrate configured as a load bearing substrate for a walking human;
a heel keel member including a second resilient substrate extending from the frame to the posterior heel end, the second resilient substrate configured as a load bearing substrate for a walking human;
a brake configured to resist a force in a vertical direction from inferior to superior with respect to the prosthetic leg;
a third resilient substrate having a first end and a second end, the first end extending vertically proximate to the brake and coupled to the brake, the second end of the third resilient substrate coupled to the forefoot keel proximate to the anterior toe end;
a guide configured to direct the travel of the first end of the third resilient member in the vertical direction responsive to force on the second end that results from dorsiflexion,
wherein the second end of the third resilient substrate is disposed above a top surface of the first resilient substrate of the forefoot keel member proximate to the anterior toe end.
