Blisters are small pockets of fluid that form when skin is repeatedly rubbed or irritated—most often from tight or poorly fitting shoes, moisture, or prolonged periods of walking or running. Although somewhat annoying, they have a purpose: they act as the body’s natural cushion to protect the damaged skin underneath. Here's more helpful information from the experienced podiatrists at Neville Foot & Ankle Centers in the Greater Houston area.

How Can I Treat a Blister?
Blister care focuses on protecting the affected area, reducing friction, and keeping the skin clean to allow for safe and comfortable healing.
You can soothe ordinary blisters with vitamin E ointment or an aloe-based cream. New skin will form underneath the affected area, and the fluid is simply absorbed. Don't remove the skin over a broken blister. The skin underneath needs this protective cover.
Also, don't puncture a blister unless it's large, painful, or likely to be further irritated. If you have to pop a blister, use a sterilized needle. To do this, put the point in a flame until it's red hot, or rinse it in isopropyl alcohol. Gently wash the area, then make a small hole and ease out the clear fluid. Apply a dab of hydrogen peroxide to help protect against infection. However, if the released fluid is white or yellow, the blister is infected and needs medical attention.
What Are the Best Ways to Prevent Blisters?
Here's our advice to keep these irritating issues at bay:
- Break in new shoes gradually. Wear them for short periods at first so your skin and the shoe can adjust before longer walks or workouts.
- Reduce friction before it starts. Apply a thin layer of petroleum jelly or use moleskin/adhesive bandages on common “hot spots”: heels, toes, and the sides of your feet.
- Choose socks that fit your foot shape. Socks with a defined heel and snug fit are less likely to slide or bunch than tube socks, which can create rubbing.
- Pick the right materials for your activity. Acrylic or other synthetic-blend socks can wick moisture and help limit rubbing, especially during sports or long days on your feet.
- Keep feet dry. Change damp socks, use foot powder if you sweat heavily, and let shoes dry out between wears to reduce moisture-related blistering.
- Practice good foot hygiene. Wash and dry your feet well after wearing synthetic socks or sweaty shoes to lower the risk of Athlete’s foot and skin irritation.
