This holding structure, susceptible of being used both as a prevention means and as a curative means comprises three parts hinged between each other, respectively: a first rigid part (1), called rod and intended to surround partially and bear against the lower end of the user's leg and, subdivided in the terminal area into two branches (4, 5) and terminated at the two malleoli of the user's ankle; a second part called pedal shell (13) intended to surround the plantar arch; and a third part called sub-astragalian shell (6) having a V-shape and intended to be hinged respectively at the malleoli to the rod (1), at the two ends (8, 9) of the branches of the V so as to provide for the displacement of said rod (1) in the sagittal plane of the tibio-tarsal articulation and, on the other hand, at the upper end of the pedal shell (13) at the point of the V so that the pedal shell (13) may effect eversion and inversion motions with respect to the assembly formed by the rod (1) and the sub-astragalian shell (6).
