For the benefit of practitioners and patients alike, all of KLM’s Rx Foot Orthotics can be made by shoe size. Yes, that means all of the Sport, Fashion, Geriatric, Pediatric and Diabetic custom orthotics. If for whatever reason, casts of the patient’s feet are not available, or the patient cannot afford custom orthotics, simply check the box labeled “California Preform” in the upper right hand corner of KLM’s Rx form and include the patient’s shoe size. Also, enjoy the California Preform discount! Questions? Don’t hesitate to contact our world class customer service team by email at email@example.com or by phone at 800-556-3668.
