A new pair of shoes should be exciting. A summer walk should be something you look forward to, not something you end early because your heel is burning. That familiar rubbing can quickly turn into a painful blister.
Blisters are common after long walks, hikes, travel or wearing new footwear, especially when repeated friction puts extra pressure on your feet. The good news is that a few simple precautions can help prevent them, while the right care can protect a blister and support healing when one does appear.
Here’s what causes blisters, how to prevent them and what to do when you get one.
What Is a Blister and What Causes It?
A blister is a small pocket of fluid that forms between the layers of skin, usually after repeated friction or pressure. When your skin repeatedly rubs against footwear or another surface, the affected area becomes irritated and the layers can separate. Fluid then collects underneath, helping protect the damaged skin while it heals.
Blisters commonly develop on the heels, toes and soles of the feet, where friction and pressure are often greatest. They can also form on other areas of the body when skin is repeatedly rubbed or irritated.
While friction is the most common cause, blisters can also result from burns, allergic reactions and certain skin conditions. The advice in this guide focuses on ordinary friction blisters.
How to Prevent Blisters
A few simple changes to your footwear and routine can help reduce friction before it causes a blister.
Choose Well-Fitting Footwear
Shoes that are too tight can create pressure points, while loose footwear can allow your feet to move around inside the shoe. Both can increase friction.
Choose footwear that feels comfortable and gives your toes enough room to move without your heel slipping excessively. When breaking in new shoes, wear them for shorter periods at first rather than taking them straight on a long walk.
Wear Comfortable, Well-Fitting Socks
Socks should fit securely without bunching, slipping or creating pressure points. Excess moisture can also increase friction, so change damp socks when needed during longer walks or activities.
Before heading out, check for wrinkles or seams that could rub against your skin. A small irritation can become much more noticeable after hours of walking.
Protect Areas Prone to Rubbing
If you regularly develop blisters in a particular area, protect it before friction becomes a problem. A blister prevention stick can help reduce rubbing on areas prone to friction, while blister cushions can provide additional protection for pressure points.
What to Do When You Get a Blister
Even with good preparation, a blister can still develop. Wash your hands before touching it, then gently clean the area and pat it dry. Avoid unnecessary rubbing or pressure, and stop using the footwear or equipment that caused it.
If the blister is intact, leave it alone rather than deliberately breaking the skin. The skin covering it helps protect the area underneath and reduces the risk of infection.
A Compeed blister plaster can cushion the affected area and help protect it from further rubbing while it heals. Follow the product instructions for correct application and use.
Should You Pop a Blister?
For a typical friction blister, it's best not to pop it yourself. Breaking the skin removes its natural protective barrier and can increase the risk of infection.
If a blister breaks on its own, don't peel away the remaining skin. Gently clean the area and cover it with a suitable dressing. If a blister is unusually large, very painful or making it difficult to walk, ask a pharmacist or healthcare professional for advice rather than trying to drain it yourself.
How to Help a Blister Heal Faster
Most uncomplicated friction blisters heal naturally within about a week, although larger blisters or those exposed to continued friction may take longer.
Give the affected area time to recover, and avoid picking at the skin or peeling it away if the blister breaks. Comfortable footwear can help prevent further irritation while the skin repairs itself.
If the blister is becoming more painful rather than improving, or you notice increasing redness, swelling or pus, seek advice from a pharmacist or healthcare professional. These can be signs that the blister is not healing normally.
When Should You Get Professional Advice?
Most ordinary friction blisters can be cared for at home, but some need professional attention. Speak to a pharmacist or healthcare professional if a blister:
-
Becomes increasingly red, hot, swollen or painful
-
Contains green or yellow pus or other unusual discharge
-
Keeps coming back or isn't healing as expected
-
Appears without an obvious cause
-
Causes severe pain or makes it difficult to walk normally
You should also seek professional advice if the blister was caused by a burn, scald, sunburn or allergic reaction, as these may need different treatment.
If you're unsure whether a blister is healing normally or showing signs of infection, a pharmacist can help you decide what to do next.
Blister Care for Walking, Hiking & New Shoes
Long walks, hikes and new footwear can put extra friction on your feet, so it's worth having blister protection ready before you set off.
Before You Go
-
Check that your footwear feels comfortable and doesn't rub.
-
If you're breaking in new shoes, avoid wearing them for a long hike straight away.
What to Pack
Keep a few blistercare essentials in your bag, especially for longer walks or hikes:
-
Compeed blister plasters for protecting blisters from further friction
-
Blister prevention stick for areas prone to rubbing
-
Blister cushions for added protection around pressure points
-
Spare socks if your feet become damp
If you notice a hot spot while walking, stop and protect the area early rather than continuing until a blister develops.
Protect Your Feet Before Your Next Walk
A painful blister doesn't have to put a stop to your plans. Preparing your feet before a long walk, hike or day in new shoes can help you stay comfortable and enjoy the journey.
