Foot blisters, those small, fluid-filled bubbles that appear on the skin, can cause discomfort and pain. Whether you are an avid hiker or someone who just enjoys an occasional walk, understanding the causes of blisters on the foot how to treat them, and how to prevent them can make your journey smoother and more comfortable.
A blister is a tiny sac of fluid that develops in the outer layers of the skin. The type of fluid inside can be serum, plasma, blood, or pus depending on the cause and nature of the blister.
Friction blisters are the most common and usually occur when the skin is repeatedly rubbed, as with tight shoes or during physical activities like running. The outer layer of the skin separates from the inner layers, and body fluid accumulates in the space to protect the tissue underneath. The fluid acts as a natural cushion, which helps to reduce pressure and irritation to the delicate tissue layers below.
Foot blisters can be attributed to various factors:
Most blisters heal on their own within 3 to 7 days if not subjected to additional irritation or infection. The healing process of a blister involves the body’s natural response to protect and repair the skin. Here’s an expanded explanation of the process:
Day 1-3: Fluid Accumulation: When a blister forms, the body sends fluid to the damaged skin to protect it. This fluid is essentially plasma, which accumulates between the upper layers of the skin, causing a raised bubble. The body uses this as a natural cushion to protect the tender skin beneath from further damage.
Day 3-5: Reabsorption and New Skin Formation: Around the third day, the body begins to reabsorb the fluid in the blister. At this point, new skin starts forming underneath the blister. The blister may begin to decrease in size as the fluid gets reabsorbed, and the area may start to dry out.
Day 5-7: Drying and Flattening: As the new skin continues to develop under the blister, the top layer of the blister starts to dry out and flatten. It is crucial during this period to avoid picking at or peeling off the blister’s skin, as the skin underneath may still be sensitive and prone to infection.
Day 7 onwards: Complete Healing: By the seventh day, most blisters should be healed. The dead skin from the blister will eventually fall off naturally. The new skin underneath is usually slightly red or pink but will gradually return to a normal colour over time.
It’s usually best to not pop a blister, as this can increase the risk of infection. However, if the blister is large and in an area where it’s likely to burst, it might be necessary to carefully drain it to avoid further discomfort.
To support the natural healing process, it’s important to follow these guidelines:
Keep it Clean: Ensure the blister and surrounding area are clean to minimise the risk of infection.
Protect the Blister: Use a bandage or blister plaster to protect the blister from additional friction. You can use special gel padding for extra cushioning.
Use a Hydrocolloid based plaster: Hydrocolloid blister plasters are dressings made of exudate-absorbent hydrophilic gel. When applied to a deroofed blister that is releasing fluid, the hydrocolloid material absorbs the liquid and transforms into a gel. They aid in maintaining a moist wound environment, absorb wound fluids and promote natural healing by helping with autolytic debridement. Plus, they provide a barrier against harmful micro-organisms and help manage pain.
Avoid Further Irritation: Refrain from wearing shoes or using equipment that caused the blister in the first place. If you must wear shoes, make sure they are well-fitted and, if necessary, use heel snugs or other padding materials.
Avoid wearing new shoes for long periods: new shoes often have a break-in period. Wear them for short durations initially to avoid blisters.
Use Padding and Bandages: If you know that an area on your foot is prone to blisters, use padding or bandages to reduce friction. You can find a range of padding products here.
Wear Moisture-Wicking Socks: These types of socks can help keep your feet dry and reduce the chances of getting blisters.
It is vital to handle blisters with care to prevent complications. If you are uncertain or if the blister looks infected, it’s always a good idea to seek medical advice.

While most foot blisters are minor and can be managed at home, there are instances when it is wise to seek medical attention. If the blister is showing signs of infection such as increased redness, warmth, or pus, it’s time to consult a doctor. Additionally, individuals with diabetes or compromised immune systems should be especially vigilant, as even small blisters can escalate into more severe issues.
In some cases, people turn to alternative treatments and home remedies for relief:
Aloe Vera Gel: Known for its soothing properties, applying aloe vera gel can alleviate the pain and promote healing.
Green Tea: Soaking your blister in cooled green tea, which has anti-inflammatory properties, may reduce swelling and discomfort.
Apple Cider Vinegar: While it may sting a bit, dabbing apple cider vinegar on the blister can act as an antiseptic.
Choosing the correct footwear is crucial in blister prevention. Look for shoes that fit well without being too tight or too loose. Ensure there’s enough space around the toes, and that the shoe securely holds the heel. For activities like hiking, it’s worth investing in specialised footwear designed to provide support and minimise friction.
Foot blisters, though common, can be a source of discomfort and pain. By understanding the causes and adopting preventative measures, you can minimise the chances of getting a blister. However, if a blister becomes infected or if you have an underlying health condition, it’s essential to seek medical advice. With the right care, knowledge, and footwear, you can keep your feet happy and blister-free!
