Walking aids are described which are of simple construction but which allow for both resilience, i.e. the part of the walking aid which is gripped by the user and the ground-engaging end (3) can be resiliency pressed together, as well as a degree of angular flexibility so that the end (3) stays aligned with the ground even if the stick, crutch or the like (1) is angled relative thereto. This is achieved in particular by the use of a bellows structure (2) between the shaft (1) of a walking aid and a ground-engaging foot (3). |
