a lower front plate pierced with a central front hole, and

a front spacer disposed between said front plates,

said front plates and said front spacer being mechanically connected together, and

a lower front block attached to the frame and configured to be secured to the upper front block, and

a rear attachment mechanism comprising

an upper rear block attached to the footwear portion, the upper rear block comprising

an upper rear plate,

a lower rear plate pierced with a central rear hole and a side rear hole, and

a rear spacer located between said rear plates,

said rear plates and said rear spacer being mechanically connected together, and

a lower rear block attached to the frame and configured to be secured to the upper rear block,

wherein said upper front block and said upper rear block are integrated into said sole, and

wherein at least a portion of said sole is created by molding and is molded onto said upper front block and said upper rear block.

2 . The sports equipment device according to claim 1 , wherein the footwear portion further comprises a retaining element which extends within a plane when at rest and which is flexurally deformable and tensionally non-deformable in the plane.

3 . The sports equipment device according to claim 2 , wherein said retaining element is fixed directly to said upper front block and said upper rear block.

4 . The sports equipment device according to claim 1 , wherein the front spacer is a single part and has a closed front wall at the center of the front spacer which surrounds said front hole, and the rear spacer has a closed rear central wall at the center of the rear spacer which surrounds said central rear hole and on the front portion of the rear spacer has a closed rear side wall which surrounds the side rear hole.

5 . The sports equipment device according to claim 1 , wherein said upper front plate has front reliefs, and said upper rear plate has rear reliefs.

6 . The sports equipment device according to claim 1 , wherein said sole comprises

an outsole which has an outer face, and

an insole, which are each created by molding, said insole being overmolded onto said outsole and onto said upper front block and said upper rear block.

7 . The sports equipment device according to claim 6 , wherein said outsole has a front hole surrounded by a front wall in which said lower front plate is housed, which opens onto said outer face, and has a rear hole surrounded by a rear wall in which said lower rear plate is housed, which opens onto said outer face.

8 . The sports equipment device according to claim 1 , wherein said frame comprises an upper shell and a lower shell configured to be mechanically secured together in a removable manner.

9 . A method for manufacturing a sports equipment device, the method comprising:

providing an upper front block and an upper rear block, the upper front block comprising

an upper front plate,

a lower front plate pierced with a central front hole, and

a front spacer located between said front plates,

said upper and lower front plates and said front spacer being mechanically connected together, and

the upper rear block comprising

an upper rear plate,

a lower rear plate pierced with a central rear hole and a side rear hole, and

a rear spacer located between said rear plates, said rear plates and said rear spacer being mechanically connected together; and

manufacturing a sole in which at least a portion is molded onto said upper front block and said upper rear block such that said upper blocks are integrated into said sole which is part of a footwear portion;

providing a frame, a lower front block, and a lower rear block, and attaching said lower blocks to said frame;

fixing a movement mechanism under said frame; and

securing the lower front block to the upper front block and securing the lower rear block to the upper rear block to removably secure the footwear portion to the frame.

10 . The method for manufacturing according to claim 9 , further comprising:

before providing the upper front block and the upper rear block, manufacturing an outsole by molding,

wherein said sole comprises said outsole and an insole which is created by molding, said insole being overmolded onto said outsole and onto said upper front block and said upper rear block.
