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 connection member includes respective pairs of support blocks on opposite sides of the vertical posts with bores therethrough for shafts that also extend through the posts to enable the posts (and thus the foot pad) to laterally rotate around the shafts. The foot pads can come into parallel contact with the ground even when the vertical support to which it is connected is laterally oriented by the user. Torsion springs connected to the posts will return the posts to a central orientation relative to the connection member when the foot pad is lifted off the ground by the user.
