ABSTRACT A dual ankle spring foot ankle system comprising generally of a first and second die helical springs attached proximally to a top ankle plate and distally to a plantar base plate. The anterior and posterior springs are attachably engaged to the lower face of the lower portion of the upper ankle plate and upper face of the base plate through a helical nut for helically engaging the spring around its body portion for rigid attachment of the spring to the plate themselves, yet maintaining maximum flexion The system further includes a rear positioned flexible member extending from the upper plate to the bottom plate for serving as a "achilles tendon" and minimizing elongation of the posterior spring beyond a certain point. There is further provided a downwardly depending forward portion of the base plate for insertion into a soft foot member so that the ankle system is substantially incorporated into the foot system as the ankle is utilized. A second embodiment would include a stepped base plate for insertion into a "rigid" artifical foot for acheiving the maximum absorbtion, storing and release of the artifical ankle in the foot ankle system.
