Abstract: Sliders or end caps which are secured to the bottom ends of the legs of walkers assist an individual in using the walker on various surfaces, such as rugs, without the danger of the legs of the walker becoming snagged on the carpet and the walker becoming unstable. The sliders or end caps have a concave bottom portion which is designed to always present a “trailing edge” to the outer perimeter of the slider or end cap. This “trailing edge” will be present even as the concave bottom portion wears away from use. Thus, the “trailing edge” will prevent the slider and walker from becoming snagged by a carpet or other surface on which the walker is used.
