As a former server, I know firsthand how hard some jobs can be on the feet, legs, and lower back. Sometimes, even the best superfeet insole is only a soft cushion. But if you do have a tough job that requires you to remain on your feet for hours on-end, you definitely need more support than even the best sneaker provides. And the money you spend on a good insole today may save you countless dollars on doctors' and prescription fees later.
