6. Rearfoot design
FDI have carefully considered the design of our orthoses, particularly at the heel and navicular region of the foot. We have developed a comfortable heel cup and have not been too aggressive constructing the medial arch.
Based on personal experience, patient feedback and clinical observations, we believe an overly bulky medial arch profile can be uncomfortable. By way of proprioception it can also cause the foot to over supinate in gait leading to premature muscle fatigue.
