A support foot assembly (10) for use with a elongated load bearing device such as a cane (16) or crutch. The support foot assembly includes a mounting structure (12) having a generally planar bottom surface (12.1) and an upper surface (12.2) which, in the preferred form of the invention shown in the accompanying drawings, is provided with a large, deep generally cylindrical cavity (12.3). Securing means (14) are provided to secure the elongated load bearing device to the mounting structure, and to this end a rubber-like crutch or cane tip (18) is mounted within the cavity (12.3), the tip (18) being retained within the cavity by a rubber-like cord (22) which passes through a small aperture (12.5) below the cavity (12.3), the cord having an enlarged portion (22.1) which engages the bottom surface (12.1) of the mounting structure. Engaging means (26) project downwardly from the bottom surface of the mounting structure, the engaging means including a plurality of spaced apart bristle tufts (28), and a plurality or rubber fingers (32) interspersed among the bristle tufts. In the illustrated preferred form the rubber fingers are formed by coating alternating bristle tufts with neoprene.
