In one aspect there is disclosed a walking aid (10). The walking aid (10) comprises a support leg (12) having an operative upper end (16) and an operative lower end (18). The walking aid (10) further comprises a wheel assembly (14) for operative attachment to the lower end (18) of the support leg (12). The wheel assembly (1.4) is adapted to be pushed in a forward direction by a user resting on the support leg (1.2). The wheel assembly (14) comprises a chassis (26) supporting (i) at least one wheel (28) and (ii) a stop (30). The stop (30) is operatively adapted to co-operate with the at least one wheel (30) such that a torque applied to the support leg (12) by the user will arrest movement of the wheel assembly (14) in the forward direction.
