Add footpads: I then Frankenstein my own orthotics into every shoe, depending on the fit. Consider one of these: a very slim insert with a heel cup and slight arch (if you need arch support), heel cushion (for heel pain) or a foot “tongue” pad (use under the foot for cushion, or put on the underside of the top of the shoe to prevent sliding forward). A podiatrist can help you with custom inserts, or you can do as I do, which is buy them in bulk at the drugstore or online.
Know your foot type. In my opinion, a podiatrist would be the best way to know your foot type and what’s going on. If you can’t run out to the podiatrist, there’s a couple of neat ways to see if you have a flat foot or a high-arch foot. Wet your foot and step onto a piece of construction paper. When you make an impression, it will show you how much your foot is flattening or how high of an arch you have. You can look at a person’s foot type and see why they are having pain.
