Boots with step-in and step-out, e.g. sports boots, in particular ski boots

The combination of a boot having a boot shell with a heel region and a step-in step-out aid having an elevated position and an inserted position cooperating with the boot shell, wherein the aid is at least one elongated heel wedge displaceably mounted in the heel region of the boot shell. The aid in its elevated position protrudes out of the boot shell, and in its inserted position at least partially fills the space between the boot shell and a person's heel that has been inserted into the boot shell.
