To enable more stable kick action preventing the heel from slipping by putting a heel block less higher than heel points onto the outer edge of the rear of the heel on the shoe bottom.

A heel block 5 having a projection 6 is applied onto an outer edge 4 of the rear at the heel of an out sole body 1 having several points 2 on its bottom. The heel block 5 having a shape of boat bottom is put on over from the front part to the end of the outer edge 4 of the rear of the heel and has an inner slant edge 7 cut downward to the out sole body 1 as shown on the sketch. This inner slant edge 7 serves to keep stable the kick action until it finishes preventing the heel from slipping off concurrently the heel block 5 being buried into the ground holds the pressure from it when the heel outer edge 4 is placed. The projection 6 to put on the surface of the heel block 5 might be one as well as several as it serves to keep stable the turning round movement.
