Normal insoles and OTC (over-the-counter)
corrective devices have generic arch supports, heel lifts or heel wedges.
These types of insoles are made for an average pronation that can be
corrected without a doctor’s prescription and can be placed in shoes
and boots with little or no size modification.
Over-the-counter insoles
can be purchased at most drug stores and sporting goods stores. They
usually lift the arch and may tilt the heels. These insoles are usually
made to fit dress or athletic shoes and must be trimmed down to fit
into some boots.
