Custom molded orthotics should mean exactly that , "custom molded ". Here at the Advanced Foot And Ankle Center of San Diego we use the most accurate method of taking foot molds for foot orthotics. Digital molds have been shown to be non accurate by as much as a centimeter. The truest mold is with a plaster cast in which we get the exact shape of the foot. This is why we have so much success with our orthotics. The doctor personally applies the casting material and takes the mold. A digital X ray is used to measure out all the deformity parameters to get the most accurate prescription. There are many reasons why orthotics fail, it can stem from the method of exam and gait analysis to the measurements of the deformities. Lastly the method of obtaining the custom mold. We pride ourselves on taking out the extra time to get the best results with a plaster mold. Don't settle for second tier measurements. Come in today for an evaluation.
