To provide a long life for a heel and to enable a heel to be easily replaced by an average person by making the heel detachably round-shaped or so shaped as to maintain the same shape at a different angle and making the heel angle changeable by loosening a nut when the heel is worn unevenly in a specific direction.

A hole 6 for a bolt 4 is made in the center of a detachable heel 1 which is round-shaped or so shaped as to maintain the same shape at a different angle, with the heel 1 and a shoe body 2 connected to the bolt 4 and a nut 5, and with a connected part 3 provided with a rugged shape so as to avoid inadvertent rotation after it is tightened with the nut 5. In addition, the heel 1 is so designed that the angle can be changed freely by loosening the nut 5 and that the heel 1 can be replaced by removing the nut 5.
