The complex supinator is fortunately not often seen yet is not uncommon.

This foot has a very small parameter of range of motion which it works best around.

The barefoot picture shows that this left foot is carrying most of the weight and force towards the inside of the foot under metatarsals 1-3.

The next picture with the patient's traditional orthotic shows that the forces under the mets are redirected more towards the center of the foot and leaning slightly towards the outside of the foot under metatarsals 2-5. Note that this patient's orthotic is actually increasing the force under the center of the foot. This patient was wearing this orthotic because it resolved some of his symptoms, but was not totally comfortable to wear.

The first fitting with the SDO shows a reduction in force over the traditional orthotic, but spreads the weight and force over the ball of the foot.

After the first fit, an attempt was made to improve the fit. One half unit was eliminated (3 grams of fluid) and notice the dramatic increase in pressure in the center of the foot similar to the patient's own orthotic, but the spread is still better to the fluid action.

The last picture (third fit) was an attempt to increase the fluid by one half unit (3 grams fluid) and see the distortion taking place. While the spread of pressure is still across the ball of the foot, there is significant increase in pressure distortion.

We elected to go with the first fit.
