Blisters

Foot Blisters Buying Guide

A blister is a small pocket of fluid that forms when the upper layers of skin become damaged. On the feet, the most common cause is friction, particularly when footwear repeatedly rubs against the heel, toes or another pressure point.

Blisters are especially common when wearing new or poorly fitting shoes, walking or running for longer than usual, or when moisture allows the skin to move repeatedly against socks and footwear.

Most uncomplicated friction blisters heal naturally. Products within our Blisters collection are therefore primarily designed to reduce rubbing, cushion vulnerable areas and protect the skin while it recovers, rather than treat the blister itself.

What Products Can Help With Foot Blisters?

The best option depends on where the rubbing occurs and whether you are trying to protect an existing blister or prevent a familiar pressure point from becoming irritated.

Heel Protection Sleeves

The back of the heel is one of the most common areas for footwear to rub.

Heel protection sleeves cover the skin around this area and provide a softer barrier between the heel and the inside of the shoe. Our range includes fabric and gel-lined designs that can be worn beneath socks and footwear.

May suit:

• Repeated rubbing at the back of the heel
• New or rigid footwear
• Walking or standing for long periods
• People who regularly develop heel blisters
• Skin that remains sensitive after a previous blister

Choose a slim design that fits comfortably without making the shoe noticeably tighter.

Toe Caps, Sleeves & Protector Tubes

Blisters can also develop where individual toes rub against footwear or against neighbouring toes.

Gel toe caps, sleeves and foam protector tubes create a cushioned layer around the affected toe. Some designs cover the end of the toe, while others can be cut or positioned around a particular rubbing point.

May suit:

• Blisters on the tops or ends of the toes
• Toes rubbing against the inside of shoes
• Crowded or overlapping toes
• Repeated irritation during walking or exercise
• Sensitive skin around a healing blister

The protector should reduce contact rather than squeeze the toe more tightly inside the shoe.

Moleskin & Adhesive Cushioning

Moleskin and adhesive pads can be positioned over or around areas that repeatedly rub against footwear.

They are useful when the problem is concentrated in one particular location and you want low-profile protection without wearing a full sleeve.

Our collection includes moleskin tape and adhesive cushioning that can be cut or positioned according to the area needing protection.

May suit:

• Small recurring friction points
• Rubbing around the heel or sides of the foot
• Pressure from formal shoes
• Areas where a sleeve would be too bulky

Avoid attaching strong adhesive directly to damaged or open blistered skin unless the product is specifically designed as a wound dressing.

Heel Grips & Shoe Cushions

Sometimes the problem begins because the heel moves excessively inside the shoe.

Heel grips add padding around the rear of the footwear and can help reduce movement between the shoe and skin. This makes them particularly useful when shoes are slightly loose at the heel.

Cushions designed for high heels or formal footwear can also soften contact around common pressure points.

May suit:

• Heel slippage
• Shoes that rub during each step
• Formal footwear
• New shoes that are slightly loose around the heel
• People who develop blisters in the same place repeatedly

A heel grip will not correct footwear that is substantially too large or badly shaped for your foot.

Toe Separators & Toe-Spacer Products

When blistering develops between the toes, the source of friction may be toe-to-toe contact rather than footwear.

A slim toe separator can create a small amount of space between neighbouring toes and reduce direct rubbing while worn.

These products may be useful where friction is associated with:

• Overlapping toes
• Crowded toes
• Bunions or bunionettes
• Hammer toes
• Repeated moisture and rubbing between neighbouring toes

Make sure there is enough room inside the shoe after inserting a separator.

Moisturising Socks & Foot-Care Products

Dry or irritated skin may be more vulnerable to discomfort from rubbing, while excessive moisture can also contribute to friction problems.

Our collection includes gel-lined moisturising socks, foot creams and other skin-care products alongside physical blister protectors.

These products can support general skin care but should not be relied upon as a substitute for correcting footwear that repeatedly rubs.

Where Do Foot Blisters Commonly Develop?

Understanding where the blister appears can make it easier to identify the cause.

Blisters on the Heel

Heel blisters commonly develop when the rear of a shoe moves against the skin during each step.

Possible solutions include:

• Heel protection sleeves
• Heel grips
• Moleskin or cushioning
• Better-fitting footwear
• Gradually breaking in new shoes

If the heel is repeatedly lifting out of the shoe, addressing the fit is usually more important than simply adding thicker padding.

Blisters on the Toes

Toe blisters can result from the toes contacting the end, top or sides of the shoe.

Toe caps and sleeves can provide protection, but check that the footwear offers enough length, width and toe-box space. Adding more padding inside an already cramped shoe may increase pressure.

Blisters Between the Toes

Blisters between neighbouring toes often result from a combination of rubbing and moisture.

A slim separator or toe sleeve may reduce direct contact. Keeping socks and feet reasonably dry can also help minimise friction.

Blisters on the Ball or Sole of the Foot

Long periods of walking, running or standing can create repeated movement between the sole and footwear.

Cushioned socks, suitable insoles and well-fitting shoes may help reduce movement and pressure, but recurring sole blisters can also indicate that your footwear is not suited to the activity.

Protecting an Existing Blister

If a friction blister has already formed, the priority is to protect the area while allowing the skin to heal.

We recommend keeping the blister clean and covering it with a soft plaster or padded dressing. Hydrocolloid blister dressings can also protect the area, reduce pain and support healing.

You should generally:

• Keep the area clean and dry
• Protect it from further rubbing
• Cover it with an appropriate plaster or dressing
• Wash your hands before touching a burst blister
• Allow fluid from a naturally burst blister to drain before covering it

The NHS advises not deliberately bursting a blister or peeling away the skin covering it.

Protective sleeves, pads and footwear accessories can be useful for reducing further friction around the area, but they are not replacements for a suitable blister dressing where the skin needs covering.

How to Prevent Friction Blisters on Your Feet

Reducing repeated movement between the skin and footwear is the main goal.

Useful measures include:

• Wearing comfortable, correctly fitting shoes
• Breaking in new footwear gradually
• Wearing suitable socks during walking or exercise
• Changing damp socks when necessary
• Protecting known rubbing points before longer activities
• Using heel grips where mild heel slippage is the problem
• Ensuring your toes have enough room
• Avoiding footwear that repeatedly causes the same blister

We recommend well-fitting footwear, gradually wearing in new shoes and suitable socks for people who regularly develop friction blisters.

Choosing the Right Blister Protection

• If your shoes rub the back of your heel – Consider a heel protection sleeve, heel grip or adhesive cushion. A heel sleeve protects the skin directly, whereas a heel grip works from inside the shoe to reduce movement and add padding.
• If one toe keeps rubbing – A toe cap, sleeve or foam protector tube can provide localised cushioning. Check the shoe as well. Repeated toe blistering can mean there is insufficient room at the front.
• If two toes rub together – Try a slim toe separator or toe-protection sleeve to reduce direct contact. Avoid using a bulky separator in already narrow footwear.
• If you know where a blister usually forms – Applying moleskin or suitable cushioning before prolonged walking or exercise can help protect a predictable friction point before the skin becomes irritated.
• If your heel slips inside the shoe – A heel grip may be more appropriate than cushioning the skin alone because it addresses some of the movement causing the rubbing.

Frequently Asked Questions About Foot Blisters

What causes blisters on the feet?

Most foot blisters are caused by repeated friction, where footwear or socks continually rub against the same area of skin.

Poorly fitting shoes, new footwear, prolonged walking or running and sweaty feet can all make friction more likely.

Should I pop a blister?

Generally, no. The NHS recommends allowing a blister to heal naturally rather than deliberately bursting it. The intact skin provides protection while the area underneath recovers.

If a blister bursts by itself, keep it clean and avoid peeling away the remaining skin.

What should I put over a blister?

A soft plaster, padded dressing or suitable blister dressing can protect the area while it heals.

Hydrocolloid dressings are another option and may help protect the blister while reducing discomfort.

Can heel grips prevent blisters?

They may help when blistering is caused by mild heel slippage inside the shoe.

By reducing movement and adding cushioning around the rear of the footwear, a heel grip can lessen repeated rubbing. Shoes that are significantly too large, however, should be replaced with a better-fitting pair rather than relying on grips alone.

Can toe caps help prevent blisters?

Yes, when repeated friction occurs around an individual toe.

A gel or foam toe protector creates a barrier between the skin and the surface causing the rubbing.

Make sure there is enough space inside the shoe for the protector.

How can I prevent blisters when walking or running?

Start with well-fitting footwear and suitable socks.

Break new shoes in gradually, change damp socks where necessary and protect known rubbing points before longer activities.

If the same blister appears repeatedly, investigate why that specific area is moving or experiencing pressure rather than simply treating the blister each time.

How long do blisters take to heal?

Most uncomplicated blisters heal naturally within approximately one week, although the exact time varies with their size, location and whether the area continues to be irritated.

Avoid the footwear or activity that caused the blister where possible until the skin has recovered.

When should I seek professional advice?

Get medical advice if a blister is very painful, keeps returning or shows signs of infection, such as heat, increasing redness or green or yellow discharge.

Professional advice is also appropriate when several blisters appear without an obvious cause, or when blistering results from burns, allergic reactions or another medical condition rather than ordinary friction.
