Squeaky Orthotics occur because of friction from the device in your shoes. Some very simple solutions is to lubricate. Apply a generous amount of talcum powder under and over the device or rub a candle around the edges.
If that doesn’t work try these alternatives:
Apply duct tape or moleskin to the underside of the distal end of the orthotic. The tape reduces the abrasion friction of the orthotic against the insole, eliminating the squeak.
Another great way to stop the squeak and deodorize your running shoes at the same time is to simply put a dryer sheet under the device.
