The ankle portion can attach to the forefoot portion, and can extend rearwardly through an upper attachment section, downwardly through an ankle section, forwardly under the ankle section of the forefoot portion, and rearwardly to a heel section, in a substantial s-shaped profile. The lower footplate can attach to the ankle or forefoot portion, and can extend through a heel section, an arch section, and to a toe section.
