An equilateral foot bed and a system using the equilateral foot bed are provided for treating foot injuries and deformities, while allowing the patient to remain ambulatory. Embodiments include a foot bed having a first portion and a second portion, the second portion having a greater thickness than the first portion. The portions of differing thickness support, align and cushion portions of the foot. The foot bed is selectively usable in either a left foot-receiving or a right foot-receiving configuration.
