About Orthotic Insoles
Orthotic insoles are inserts that go into shoes or boots to correct flat feet and provide arch support. "Flat feet" means that the arch of the foot is flat--it's a very common disorder that can appear at birth or, in women, after pregnancy. Flat feet is a painless condition and usually causes no serious problems, although sometimes it can cause pronation (a condition in which the foot rotates inwards). Orthotic insoles support the arch of the foot when standing or walking and correct for flat feet. They come in men's and women's sizes, matching shoe sizes. Doctors sometimes prescribe orthotic insoles, but no prescription is required by law to buy them. Some orthotic insoles are advertised as "medical quality." They consist of various flexible and buoyant gels and other materials. Orthotic insoles are readily available on eBay from reliable vendors. If you have flat feet and want to correct the problem, this is what you're looking for.
