Abstract
A level is adapted for attachment to an upper surface of a shoe in such a manner that the level is visible to a wearer of the shoe. The level is calibrated by using a known level surface to stand upon and then adjusting the level so that it reads level when standing on the known level surface. The user then walks intermediate a first and second location, pausing as desired, and noting the reading that is provided by the level. Accordingly, a method of determining the grade at any given location is provided. If the user combines two or more readings that are taken intermediate the first and the second location, an average grade intermediate the first and the second location is provided. A preferred bubble level and method of adjusting the level to the shoe and of detaching it therefrom is disclosed.
