An artificial ankle system which is mounted within an artificial foot, such as a S.A.C.H. foot, with the ankle system comprising upper and lower plates, having a pair of spaced apart solid compressible members known as bonded rubber springs, which are attached to the upper and lower plates via gluing or the like, the rubber spring and plate system boltingly attached to the lower portion of the foot, and attached to a prosthesis to the upper prosthetic portion of the leg. This system further provides at least a posterior strap member secured around the upper and lower plate, the strap member serving as a means for compressing the posterior rubber spring to a certain degree, so that it is pre-compressed while being utilized in static or standing position, but allowing the rubber spring to also function in tension or elongation to a predetermined point. There may be further included an anterior strap, which likewise would compress the anterior spring as a strap that is fitted around the upper and lower plates. Those portions of the upper and lower plates resting above the anterior rubber spring.
