Abstract: A training device that is a rigid and substantially flat, thin platform is described. The outline of the platform is about the size and shape of a user's foot or footprint to provide visual and tactile feedback regarding the position and orientation of the user's foot. The platform may have surface features on the upper surface, which along with edges of the platform can be sensed by the user for providing the tactile feedback while the user is stepping and/or standing and exercising on the platform. The platform may have a non-slip lower surface using high friction material and/or or spikes or pegs extending from the lower surface for gripping a training surface and removably securing the platform laterally to the training surface. The platform may be lifted from the training surface with minimal effort and repositioned on the training surface.
