A crutch-like mobility assist device includes a vertical support assembly, an underarm support mechanism, and a rotatable footer assembly, the rotatable footer assembly including an elongated ground-engaging foot pad, attachment members connected to the foot pad and having vertical posts, and an elongated connection member with openings through which the vertical posts extend. The sharpened side has a first sharp portion and a second sharp portion. The wear ring is mounted to the retainer ring and extends downwardly therefrom to define a wear ring bottom face positioned downwardly relative to the plug body seating surface. By adding the capability of planarizing the elements, they can be combined in a final structure on a roll-to-roll process. The loader also comprises an actuator to actuate the rotational movement of the front transverse shaft.
