Further, other structural aspects of the heel component 121 can be altered to change the elastic stiffness response laterally across the foot. In addition, one or more secondary arch components 121 can be provided on the interior aspect of the heel component(s) for increasing elastic stiffness (e.g., FIG. 3b).
