A walking aid comprises a shaft and a foot assembly, in which the foot assembly includes in combination a sleeve member and a foot member adapted for relative axial sliding movement and including resilient movement-restraint means, the sleeve member being adapted for attachment to the shaft and including grip means for inhibiting or preventing removal from the shaft once attached thereto. The resilience may be adjustable and the foot member is preferably free to swivel within the sleeve member. The assembly may also be used as a castor, for use for example in shopping trolleys.
