What about Supinators?

Posture Control Insoles® are not recommended for people who hypersupinate because of structural or neuromuscular abnormalities typically manifested by abnormally high (peaked) arches (Cavus feet). This group of patients is fairly small.

There is another less documented group that includes about half of the patients presenting with Rothbart's foot structure. A large number of patients who hyperpronate while standing, supinate when they walk or run. During a time, when the foot should be released to pronate, these patients muscularly brace their feet to hold them in a supinated position. This can be clearly observed from checking the wear pattern on their shoes.

This group of patients do not present with structural deformities or anomalies indicating a supinated gait. For generally unknown reasons these patients brace their muscles in an attempt to maintain a supinated foot. This may be a subconscious over-correction in response to hyperpronation, but to our knowledge, no study of this phenomenon has been done. By all appearances, the first metatarsal and big toe are not part of the supination caused by "bracing". Patients who "brace" typically present with calf pain and shin splints indicating that other muscle groups are trying to compensate for the unstable foot.

This group of patients also respond well to Posture Control Insoles®, but the forces are initially kept low (start in 3.5mm) to initiate a relaxation of the muscular bracing pattern. Once the bracing pattern starts to relax, the forces can be increased in accordance with the first metatarsal deficit (elevation of the first metatarsal).
