Once Otis begins inspecting the boots, they would appear to be perfectly mundane boots. Even the winged heels would appear to be purely ornamental, and attempts to sift through the essences of the boots would find only mundane concepts like "flexible" and "durable" from the leather, or "aerodynamic" from the wings. There are no indications that this is special at all, but rather regular boots with a flashier design.
