Abstract
Footwear (210) that is readily adjustable to maintain the wearer in an upright, substantially vertical position, enabling the wearer to negotiate a steep roof without slipping or falling. The footwear (210) entails a pair of shoe boards (224) that attach to the wearer's shoes or feet. Each shoe board (224) is supported on a base (212) whose shape provides a large surface area that, when in contact with the roof under the weight of the wearer, securely grips the roof surface, even for roof pitches of 12/12. In addition, the shape of each base (212) is tailored to enable a pair of the footwear (210) to nest together, allowing the wearer to place his or her feet close together when desired. In a preferred embodiment, each base (212) is equipped with concave surface regions (228B, 232B) that receive convex portions (228A, 232A) of its mating shoe board (224) in a manner that provides an uncomplicated method of adjusting the pitch of the footwear (210) and securing the shoe board (224) to the base (212).
