Abstract: A walker frame of the type including four legs which extend into contact with the ground and support an upper handgrip portion is modified by the provision of a skid member attached to at least the rear legs for engagement with the ground. The skid member includes a portion of a flat strip material manufactured from a high density plastic material with the front edge of the skid member turned upwardly to allow ready sliding over various surfaces. The flat strip is attached to the lower leg by an insert member which expands in the hollow interior at the lower end of the leg by screws passing through the skid member from the underside into the leg.
