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 (1b) 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).
