Blisters are the accumulation of fluid between the skin's inner and outer layers. They are rarely serious but can become infected and force a layoff from running if not treated properly.
Prolonged friction between your foot, socks and shoes creates blisters.
A blister should be opened as soon as possible. Then the skin layers will adhere together, and you'll be running pain-free the next day. Swab the blister with alcohol or other antiseptic solution and prick it with a needle heated in a flame. Drain the fluid, but leave the skin. Then cover the area with an adhesive bandage. Within 48 hours, most blisters are dry enough to expose them to the air.
If you are susceptible to blisters, try wearing dual-layer or blister-free socks to minimize friction and moisture. (Socks made from breathable synthetics work especially well to keep your feet dry). Also, over-the-counter neoprene insoles can reduce friction. Break in new shoes gradually, and make sure you're wearing shoes that fit properly and are correct from a biomechanical point of view, as too much foot motion can cause friction. A shoe that is too tight will also cause considerable rubbing.
