Casting Instructions Accuthotix™ works with semi-weight bearing position, sub-talar neutral foam impressions. Our research indicates that this technique affords a fast, clean, simple and effective method for capturing the foot with ideal sub-talar joint positioning. Each impression is filled with plaster, which is then used to mold the shell of the orthotic. Every orthotic is hand-made in our laboratory. Because the most common cause for orthotic failure is incorrect positioning of the foot during the casting process, it is essential that the negative impression be accurate.

The impression should be about 2 inches deep with even depth at the forefoot and the rear foot. 6.  Remove the patient's foot from the foam impression and make sure that the depth of the rearfoot and forefoot are equal. The contour of the medial longitudinal arch should appear uniform. 7.  Repeat procedure with patient's other foot.
