First determine what type of feet you have. Here is a quick test you can do at home to know your foot type.
High Arch: You may underpronate (land on the outside of your feet), which can cause too much shock to travel up your legs. Look for a neutral or cushioned shoe.
Normal Arch: You probably have few foot or pronation problems. A neutral shoe is your best bet.
Flat Arch: You likely overpronate (your feet turn inward too much). Try neutral or stability shoes.
Now go to a knowledgeable store clerk and tell them your foot type and they can help you select the best runner.
