I have suffered with flat feet my whole life and have tried various items to help... most do little or nothing to help ease my uncomfortableness... someone suggested trying this brand by a personal recommendation so I purchased some...These are very comfortable giving the foot proper support without tilting the foot to the outside as other orthotics have done. That wears the outside edges of the soles out prematurely. This is my second set since I iked the first set so much. Nicer to have a few pairs so I never have to worry about going without again
