ABSTRACT:
The invention comprises a product of and a method of using a raised platform which preferably has two pairs of sides. One pair of sides converge to define a protrusion and to accommodate feet which are turned inwardly; the other pair of sides recede to define an opening and to accommodate feet which are turned outwardly. Each side in a pair of sides is separately configured so the user can place his foot on the platform when the foot is turned inwardly or outwardly. The platform is supported above a lower surface by legs.
