This prosthetic foot structure comprises two separate spring blades (3, 4), deformable independently of one another, the first blade (3) extending substantially from below the malleolar recess (2) to the front end of the body (1) and being inclined from the rear to the front of the body (1), while the second blade (4) is disposed at the rear of this body, substantially below the 'malleolar recess (2), and has, in section through a longitudinal vertical plane, a lying U-section of which the two branches are directed towards the rear, the upper branch being in contact with the lower or upper face of the rear part of the first blade (3) and being rigidly integral with the latter.
