No one else's feet are exactly like yours. If your feet are contributing to a postural problem in another part of your body (or if your body is putting stress on your feet), your chiropractor may need to perform corrective foot adjustments. Each pair of custom -made flexible Orthotics is created for the individual supports all three arches of your feet, and is designed specifically to help your doctor's adjustments "hold" better. "Off-the-rack" shoe inserts are mass-produced and cannot provide the specific level of support so you may need to keep your feet in their proper structural positions.
