Then the outsole 12 (or sole 10) is translated rearward relative to the chassis 30 until the distal end of the tab 51B passes over the front edge of the central front hole 521H, in order to secure this tab 51B to the upper front block 50H.
  • the rear of the outer sole 12 (or sole 10) is lowered vertically against the rear of the upper face of the chassis 30 until the hooks 64B enter the rear center hole 621H of the upper rear plate 62H.
  • the tip 65B of the lower rear block 60B enters the rear side hole 622H of the upper rear plate 62H.
  • the rear edge of the rear center hole 621H then presses against the convex apex of each of the hooks 64B to push them forward against the spring 66B.
  • the rear of the outer sole 12 is continued to be brought vertically closer to the chassis 30 until the rear edge of the rear center hole 621H passes under the upper end of each of the hooks 64B.
  • the spring 66B then pushes the hooks 64B rearward so that the rear edge of the central rear hole 621H is sandwiched between the upper end of the hooks 64B and the guide 61B.
  • the hooks 64B are thus secured to the upper rear block 60H.
  • the shoe part 1 is thus secured vertically and horizontally to the chassis 30 by the tab 51B and the hooks 64B.
  • the chassis 30 has a straight conduit 306 which is formed between the upper shell 31 and the lower shell 32 and which extends horizontally rearward from the rear hole 316 until it opens at the rear of the chassis 30, as illustrated in Figures 11 And 12

  • the shaft of a tool (not shown) is inserted until its end pushes forward the rear tab 632B of the carriage 63B, compressing the spring 66B. This pushes the hooks 64B forward, disengaging the rear edge of the rear center hole 621H from the hooks 64B.
  • the rear edge of the shoe-like part 1 can then be lifted away from the frame 30, and the shoe-like part 1 is then moved forward relative to the frame 30 to disengage the tab 51B from the front center hole 521H.
  • the shoe-like part 1 is thus completely separated from the frame 30.
