Abstract
Various embodiments of ladders, ladder legs, ladder feet, foot mechanisms for ladders, and related methods are provided herein. In one embodiment, a foot is pivotal relative to a leg or rail of the ladder between a first position and at least a second position. A biasing force is applied to the foot to maintain the foot in either of the user-selected positions until a force is applied to pivot the foot to another position. In one embodiment, the foot mechanism maintaining the foot at a desired position may include a pair of pins that couple the foot to another component (e.g., a housing member, an insert member or a rail of the ladder). At least one of the two pins may be displaceable relative to the other pin during pivoting of the foot.
