Abstract
Embodiments of the present invention provide a level device for a shoe in which particular portions of shoes which may easily contact and/or collide with the ground or other objects may be embraced and thus protected with a separate cover unit and, at the same time, a surface state of any given location may be visually determined, and, hence, first, the shoes may be prevented from damage and thus have improved durability, second, the separate cover unit may decorate the shoes to achieve aesthetic improvement, thereby providing high quality and/or diverse designs of the shoes, and, third, the shoe-wearer may visually determine in a simple and convenient manner whether a location where the wearer is standing is level or not and if not, the direction and extent of the grade.
