Insoles are also known as orthotics, devices used to help rectify feet problems. Insoles are used typically to treat flat feet, Achilles tendonitis, uneven feet length and many more. There are two types of insoles, the premade insoles that are sold in supermarkets and a custom made insoles to fit the patient. Custom made insoles are made by technicians with a prescription from a podiatrist, and they cost up to ten times more than a normal store bought pair.
However, if a person has severe flat feet, more serious problems such as bunions, uneven feet length or have back problems, then the insoles would generally have to be custom made. In addition to being made to fit, there is a choice for some less severe injuries to have a slim pair of insoles that could fit in dress shoes without looking obvious. Custom made insoles are made from plastic, polypropylene or ethylene vinyl acetate foam or a combination of both.
Another benefit to having custom made insoles is the freedom to chose the covering, from vinyl to leather, the choice is based on usage and appearance. While custom made insoles are more expensive than store bought ones, they offer better comfort and last longer. The decision should be made on affordability and the severity of the condition, and the long term outlook for the person need a pair of insoles.
