What is a Foot Blister?

Blisters usually form on the feet due to rubbing and friction with clothing, shoes or the ground. But, there is no need to worry about foot blisters, as they are easily curable. In this article, we reveal how to prevent the formation of foot blisters, the main reasons for their formation and how to treat them.

How to Prevent Blisters

  • Wear comfortable shoes that fit correctly
  • Protect vulnerable spots on the feet by taping them
  • Be careful while wearing boots that have seams inside them. Do not leave such boots near a heater or on a radiator as this can cause the seams to protrude.
  • Ensure your feet are always dry and get out of wet socks and shoes as soon as possible
  • Use foot powder to keep your feet dry and keep changing your socks every day

Foot Blisters due to Running

Long distance runners commonly develop blisters. These athletes can try the following tips to avoid foot blisters:

  • Break in new running shoes steadily and gradually
  • Wear double-layered socks to avoid friction against skin
  • Apply petroleum jelly on vulnerable areas as this can help to reduce friction
  • Use zinc oxide tape to protect vulnerable spots from friction

About Blood Blisters

Blood blisters usually form when a blood vessel is damaged causing bleeding into skin tissues. Unlike normal blisters which form due to repetitive friction, blood blisters usually form due to skin pinching or a sudden impact.

Treatment of Foot Blisters

  • Usually small blisters heal on their own if left alone
  • As soon as a foot blister appears, put a plaster over it and then tape it
  • Make sure your feet remain dry and keep changing socks regularly
  • To relieve pain, apply petroleum jelly

Popping a Foot Blister

Larger blisters and those that cause problems can be popped, but with caution. You should follow these guidelines when popping a foot blister:

  • Use a sterilized needle or pin to make a small hole on the blister, but do not try this on a blood blister.
  • Drain out the fluid but leave the skin on the wound. This is important to protect the underlying skin and prevent infection.
  • Use a sterile wipe to clean the foot blister
  • Apply a blister plaster over the wound
  • Then apply tape on it for extra security


Avoid playing barefoot especially on sun-baked surfaces to avoid foot blisters. As this article reveals, proper care and self treatment are enough to treat most blisters as this condition is rarely serious.
