Abstract
A ladder shoe for providing enhanced stability between a ladder and a variety of surfaces. The ladder shoe is comprised of a shoe body having a first side plate, a second side plate and a base. The first side plate and the second side plate are attached to the base. The side plates include curved slots through which a fastener is disposed which movably connects the ladder shoe to the end of the ladder's side rail, thereby allowing the ladder shoe to move between a first position where the base is at a first angle with respect to the side rail and a second position where the base is at a second angle with respect to the side rail. Each slot has a notch in which the fastener catches causing the shoe to be maintained in an intermediate position until the shoe body is desired to be placed into another position. The base has a bottom which provides a slip resistant surface for engaging the shoe body to essentially flat surfaces when the shoe body is in the first position. Preferably, a spur plate is provided for engaging the shoe with penetrable surfaces when the shoe body is in a second position extending from the base. There is also a method and system involving the same.
