*The rowel, seen on some spurs, a revolving wheel or disk with radiating "points" at the end attached to the shank.

Spurs are usually held on by a leather or leather-like spur strap that goes over the arch of the foot and under the sole in front of the boot heel. Some western designs have a leather strap that goes only over the top, with a heel chain or a rubber "tiedown" instead of a strap under the boot.
