Blisters are most commonly caused by friction and burns.  We would generally recommend that you try to keep the blister intact to reduce the risk of infection.  The unbroken skin over a blister provides a natural barrier to bacteria thus decreasing the risk of infection.


To Treat:


Cover a small blister with an adhesive bandage, and cover a large one with a porous, plastic-coated gauze pad that absorbs moisture and allows the wound to breathe.


If you have diabetes or poor circulation, call your doctor before considering the self-care measures below.


To prevent a blistering, use gloves, socks, a bandage or similar protective covering over the area being treated. Special footcare products are available that have extra padding in critical areas. You might also try attaching moleskin to the inside of your shoe where it might rub, such as at the heel.


Shoe-shopping tips


Remember the following when you shop for shoes:


  • Shop during the middle of the day. Your feet swell throughout the day, so a late-day fitting will probably give you the best fit.
  • Wear the same socks you’ll wear when walking, or bring them with you to the store.
  • Measure your feet. Shoe sizes change throughout adulthood.
  • Measure both feet and try on both shoes. If your feet differ in size, buy the larger size.
  • Go for flexible, but supportive, shoes with cushioned insoles.
  • Leave toe room. Be sure that you can comfortably wiggle your toes.
  • Avoid shoes with seams in the toe box, which may irritate bunions or hammertoes.
