  • the present invention is not limited to this, and the air groove 41 may not be provided in the side surface portion.

That is, the plurality of suction cups 13 can hold the vacuum state in a redundant manner, and the entire bottom can be brought into a vacuum state by surrounding the entire bottom with side portions. Further, the heel cover 1 is difficult to come off due to the frictional force between the inner surface of the side surface portion and the outer surface of the flange portion S1.
  • the heel cover 1 preferably further includes an adjustment member 70.
  • the adjustment member 70 is made of the same material as the fitting portion 11 and has a thin kamaboko-shaped cross section in which one side surface is a flat surface and the other side surface is a cylindrical surface. It is preferable that the height of the adjustment member 70 is substantially the same as that of the flange portion S1.
  • the shape / size of the adjustment member 70 may not be described here, but may be other shapes / sizes.
  • the adjustment member 70 is bonded to the heel cover (main body) 1 with an adhesive or the like. Furthermore, it is preferable not to include the adjusting member 70 as a separate member but to include an adjusting member 71 (one-dot chain line in FIG. 19) that is formed integrally with the heel cover 1 in advance.
