Will shoe inserts help if I have flat feet?

Nonsurgical option. There a a number of nonsurgical options that can be tried depending on the stage of the flat foot. These range from wedge cushions for the heel, arch supports/orthotics, braces, and boots.
Yes. Specialized shoe inserts, such as the superfeet brand, do help persons with flat feet. The inserts have a firm, supportive underside, and a softer foam topside. They help hold up the person's flattened arches.
