A supportive stability orthotic for narrow feet can be difficult to find. Many over-the-counter shoe inserts offer soft cushioning that feels good for the moment but neglect to provide any functional corrective action. Still others are simply a waste of money because they wear quickly, are uncomfortable or make no difference at all.
In the past, getting a custom narrow shoe insert to correct your foot alignment meant a visit with a podiatrist, making inserts highly cost restrictive. While some people do truly require prescription correction and doctor supervision, many everyday foot problems can be corrected with an orthotic that takes just a few measurements into account.

KLM Labs studied thousands of foot orthotics manufactured for foot care professionals all across the nation. After careful analysis, we were able to draw the conclusion that 99 orthotic shapes were used 70 percent of the time. That means that it's possible to create an insole specific to your needs without expensive molds or prescriptions.
Our System Rx shells allow you to order an orthotic sized to your foot's length, heel width, and arch heights, and at the correct rigidity for your weight and activity level. These are the components responsible for correcting your foot's alignment and your gait cycle.

While walking and running, the entire weight of your body is transferred through the bones, ligaments and muscles of the feet and ankles in a process called the gait cycle. This is where repetitive incorrect alignment can cause long-term damage, and where a simple supportive orthotic can help prevent said damage. The orthotic insole encourages the joints in the foot to align properly during the gait cycle so those forces are transferred effectively through the structures of the lower extremity.

Customizing your orthotic is quick and easy. To do so, you'll only need to watch the sizing video and download the sizing chart, then enter your sizing information using the dropdown options on each product's page. Once we receive your order, we create a supportive stability orthotic specifically for your narrow feet. The insole won't just be comfortable, it'll also provide you with proper support, stability and alignment to significantly reduce pain from pronation, supination, overuse, prolonged standing, and more.
