A boot tree has three shaped pieces: a foot piece, a front leg piece, and a back leg piece. The three pieces are mechanically connected together. The mechanical connections do not contain any hinge connecting one piece to another. The mechanical connection of the foot piece to the front leg piece contains at least one articulated compressible linking element allowing relative pivoting, backwards and forwards, of the two pieces. The leg piece has no obstacle to obstruct the pivoting of the linking element between the positions of the foot when resting and when pointed. The mechanical connection of the front leg piece to the back leg piece also contains at least one articulated compressible linking element, allowing the back leg piece to pivot upwards relative to the front leg piece. The leg pieces have no obstacles which could obstruct the pivoting of the linking element between the positions with the heel in the natural position and with the heel in the raised position.
