The needs of the cowboy's job required different tack than was used in "English" disciplines. Covering long distances, and working with half-wild cattle, frequently at high speeds in very rough, brushy terrain, meant the ever-present danger of a rider becoming unseated in an accident miles from home and support. Thus, the most noticeable equipment difference is in the saddle, which has a heavy and substantial tree (traditionally made of wood) to absorb the shock of roping. The western saddle features a prominent pommel topped by a horn (a knob used for wrapping a lariat after roping an animal), a deep seat and a high cantle. Depending on the local geography, tapaderos ("taps") cover the front of the stirrups to prevent brush from catching in the stirrups. Cowboy boots have somewhat more pointed toes and higher heels than a traditional work boot, modifications designed to prevent the rider's foot from slipping through the stirrup during a fall and being dragged.
