Running

For tarmac, look for a smooth sole and cushioning; for off-road trails, on the other hand, look for a deep tread that grips in mud and grass. You buy a running shoe a bit larger than a walking shoe, because your foot expands during exercise and your toenails would hit the front on descents. The lifespan of the cushioning is limited, which you will notice in your knees rather than by eye. Choose clothing so that you feel freezing for the first few minutes — it will balance out once you get going. For longer routes, sort out your hydration before you get thirsty.
