How can my foot blisters be treated?

If a foot blister develops, don't pop it. The skin provides a natural defense against infection. A blister should drain on its own in a few days, as a new layer of skin forms underneath the fluid. The outer layer will eventually peel away. To prevent the blister from popping, place a bandage over it, or -- for large blisters -- create a donut cushion by cutting a hole in a piece of moleskin or felt. If the blister breaks anyway, clean and dry the area and use an antibiotic ointment before covering it with a sterile bandage. If you have diabetes or a circulatory problem, it may take longer for the blister to heal on its own, and you'll be more likely to develop an infection. Consult a doctor or foot care specialist.

Try to avoid picking at the blister. This may be challenging as we all do it. However, picking at blisters may turn into infections. A blister should heel itself in time. Until that time, put a bandage on it to prevent from picking at it.

I am an endurance athlete and my main focus is on blister prevention.  Any areas on my feet that are prone to blister while running get a swab of New Skin or other liquid bandage prior to running.  I simply swipe on, let dry, and go on my way!  This works great to prevent blisters from occuring in the first place.
