The prosthetic foot (1) consists of three or four laminas, a lower lamina (1a) defining the under-heel and the foot front, a rear lamina (1 b) defining the heel and functioning as the Achilles tendon and as the soleus muscle, two upper laminas (1c and 1d) defining the front part of the foot and performing the function of the front tibial muscle, and a connector (2) in proximity to the ankle to serve as a coupling for a tube (3). The aim of this prosthetic foot is to simulate the behaviour of the human foot, in such a manner as to ensure good rear flexure and effective plantar flexure. The use of three or four laminas enables continuous energy absorption/return by the foot such as to allow assisted walking by the prosthetic foot at every moment. The prosthetic foot always operates via at least two laminas, of which one absorbs and the other returns energy. The device is arranged to be housed within an aesthetic covering.
