How to Prevent Blisters

Developing a blister can sure take the fun out of an otherwise enjoyable physical activity. The combination of heat, moisture, and rubbing that occurs during running, hiking, and other activities can cause these fluid filled bubbles to form, often resulting in pain, redness, and possible infection.

Some tips to help prevent blisters include the following:

  • Treat hot spots—Often the best way to prevent a blister from forming is to make sure that any areas of the skin that are susceptible to excessive rubbing are protected. By covering the spot with tape, liquid bandage, moleskin, or other shoe inserts, you can decrease the friction and avoid the blistering. If you notice an irritation developing during an activity, apply the same measures.
  • Proper hydration—When you dehydrate, it can cause your feet to become swollen which consequently increases friction and rubbing in your footwear causing blisters to occur. Drink plenty of healthy fluids before, during, and after exercise to maintain good hydration.
  • If the shoe fits—Poorly fitting shoes can also be a major cause of blisters. Shoes that are too tight or too loose can both lead to friction and pressure that causes blisters to develop. Always wear a shoe that is properly fitted and appropriate for the activity.

If you do develop a blister, it is important to resist the urge to pop it. The blister will heal better if left intact. If your blister pops and subsequently becomes infected, you should consult with a foot care specialist for proper treatment.
