ABSTRACT:
A medical walker foot includes a shell having a base portion for engaging a floor or the ground when weight is applied to the walker and a sleeve portion for receiving the lower end of the medical walker leg. A cup-like urethane cushion is disposed within the shell for biasing a tip member into an extended position, disengaging the base portion from the ground, and allowing the tip member to glide along the ground when weight is removed from the walker. The base portion of the shell includes a wiper seal which extends radially into the opening in the base portion to form a watertight seal with the stem of the tip member.
