Blisters - How to Treat and Prevent Blisters

Blisters can be a common and uncomfortable issue, especially on the feet, but with proper blister prevention and treatment, you can keep your feet comfortable and pain-free. Understanding what causes blisters is key to preventing them and effectively treating them when they do occur.

Causes of Blisters:

Friction: Friction is one of the leading causes of blisters. When excessive rubbing or friction occurs between the skin and another surface, such as shoes or socks, it can cause the layers of skin to separate, creating a pocket of fluid that forms a blister.

Moisture: Moisture can also be a culprit in blister formation. When the skin is wet for prolonged periods of time, such as from sweat or damp conditions, it can soften the skin and make it more susceptible to friction and blister formation.

Heat: Exposure to heat, such as from hot surfaces or direct sunlight, can cause blisters to form. Heat can increase moisture and friction on the skin, leading to blister formation.

Ill-fitting footwear: Wearing shoes that are too tight, too loose, or have rough seams can cause excessive rubbing and friction on the feet, leading to blisters.

Blister Prevention:

Proper Footwear: Wearing well-fitting shoes that provide proper support and cushioning can help reduce friction and prevent blisters. Choosing shoes with breathable materials can also help keep feet dry and reduce moisture-related blister formation.

Socks: Wearing moisture-wicking socks made of breathable materials can help keep feet dry and reduce friction, minimizing the risk of blisters. Avoiding cotton socks, which tend to retain moisture, is recommended. We recommend Carnation silver socks

Blister Prevention Patches:

Engo blister patches are a popular and effective solution for blister prevention and treatment. These innovative patches are designed to reduce friction and protect the skin, helping to prevent blisters from forming or providing relief for existing blisters. Engo blister patches are made of durable and adhesive material that adheres to the inside of shoes, socks, or other gear, creating a smooth and friction-free surface for the feet. They are available in various shapes and sizes, making them suitable for different areas of the feet, such as heels, toes, or the ball of the foot.

Protect It:  Applying a blister patch such as our Blisterpod Hydrocolloid blister plasters which work by creating a protective barrier over the blister, sealing it off from further friction and pressure, which can help prevent the blister from worsening or becoming infected. The gel-like material also helps to keep the blister area moist, which can promote healing and reduce pain. or cushioning pad can provide protection and relieve pressure on the blister, allowing it to heal naturally.

Keep It Clean: Keeping the blister clean and dry can help prevent infection. If the blister does break,, apply an antiseptic ointment, and cover it with a sterile bandage.

Seek Medical Attention: If a blister becomes infected, is very large or painful, or does not heal within a reasonable time, it's important to seek medical attention for proper treatment.

Recurring blisters in the same area are usually due to repetitive friction or pressure. This can be caused by improperly fitting shoes, certain foot mechanics (such as overpronation), or consistent rubbing during activities like running or hiking. Identifying and addressing the underlying cause, such as adjusting footwear or using protective padding, can help prevent future blisters.

9. Can foot blisters be a sign of an underlying health condition?

In some cases, foot blisters can be a symptom of underlying health issues, such as:

Diabetes: People with diabetes may be more prone to blisters due to nerve damage (neuropathy) and poor circulation.

Autoimmune diseases: Conditions like bullous pemphigoid and pemphigus vulgaris can cause blistering on the skin, including the feet.

10. What should I do if a blister bursts?

If a blister bursts:

Clean the area immediately with mild soap and water. Apply an antiseptic ointment such as betadiene to prevent infection. Cover it with a sterile bandage or dressing. Change the bandage daily, and keep the area clean and dry until it heals.

11. Can certain activities increase the risk of foot blisters?

Yes, certain activities that involve repetitive movement or prolonged pressure on the feet can increase the risk of blisters. Common examples include:

Running or hiking (especially with improper footwear)

Sports that involve sudden stops and starts, such as basketball or tennis

Standing for long periods at work or events

Wearing the right shoes, socks, and blister prevention aids can help minimize the risk.

12. Are there any complications from untreated blisters?

While most foot blisters heal without issues, complications can arise if they become infected.
