Before fitting any orthotic device, ensure the patient’s shoes are in good condition. If they are badly worn they should be replaced and any lining or insoles removed.
You can use the sizing chart provided as a guide to estimate the orthotic size based on the patient’s shoe size. For greater accuracy place the orthotic under the foot – ensuring the distal edge of the orthotic finishes 5-10mm behind the bisection of the 1st MTPJ.
