A height adjustable walking aid includes an outer tube and an inner tube slidably received within the outer tube. Adjustment is made using a, actuating assembly and pin assembly. Application of an actuation force upon the actuating assembly engages a translating member within the translating rod assembly to drive a lower pin travel block of the pin assembly from a first position to a second position. A pin then travels from an extended position to a retracted position such that the inner tube may slidably translate within the outer tube.
