If one were to define "orthotics" it might go something like this, "an orthopedic appliance or apparatus used to support, align, prevent, or correct deformities or to improve the function of movable parts of the body" (Dorland's Illustrated Medical Dictionary).  There is, however, some mis-information, and mis-representation about what an orthotic entails. it is imperative to understand the difference between several terms: Custom made Orthotics, Customized Orthotics, and Over the counter Orthotics.

Custom Orthotics: These are the orthotics that are designed from raw materials, by a qualified professional, from a mold of your foot.

Customized Orthotics: These are the pre-manufactured orthotics that are modified by a professional based upon your foot and it's problems.

Over the Counter Orthotics: These devices are pre-manufactured products that one can buy at the store and usually incorporate more cushioning than correction to feet.

Buyer be aware: Make sure that if you are paying hundreds of dollars for this product that it is made from a cast/mold of your foot and manufactured from raw materials. Otherwise it might as well be an over the counter orthotic with only cushioning in mind.
