Living with diabetes requires more than monitoring blood sugar. Your feet also need regular attention because diabetes can affect nerves and blood circulation, making it harder to notice injuries and allowing wounds to heal more slowly. Good diabetic foot care can help identify problems early and reduce the risk of ulcers, infections and other serious complications. If you notice a wound, swelling, colour change or other unusual foot problem, timely medical evaluation is important.

A simple daily routine—checking your feet, keeping the skin clean and dry, wearing appropriate footwear and avoiding preventable injuries—can make a meaningful difference.

Why Is Foot Care Important for People With Diabetes?

Diabetes can affect the feet in several ways.

One common complication is diabetic peripheral neuropathy, a type of nerve damage that can reduce sensation in the feet. You may not notice a blister, cut, burn or pressure injury because the affected area may not hurt as it normally would.

Diabetes can also be associated with reduced blood flow to the legs and feet. Poor circulation can make it more difficult for injured tissue to receive the oxygen and nutrients required for healing.

When reduced sensation, pressure, injury and circulation problems occur together, a small foot injury can potentially progress into a diabetic foot ulcer or infection.

This is why regular inspection and appropriate foot care are important even when your feet feel completely normal. NIDDK recommends checking the feet every day and having regular professional foot examinations.

Diabetic Foot Care: What You Should Do

1. Inspect Your Feet Every Day

Make foot inspection part of your daily routine.

Check the tops, soles, heels, sides and spaces between your toes. Look for:

• Cuts or scratches
• Blisters
• Redness
• Swelling
• Cracked skin
• Calluses
• Corns
• Changes in skin colour
• Ingrown toenails
• Drainage or fluid
• Areas that feel unusually warm

If you cannot see the bottom of your feet easily, use a mirror or ask someone you trust to help.

Daily inspection is particularly important if you have reduced sensation because an injury may be present without causing pain.

2. Wash Your Feet Gently Every Day

Wash your feet using warm—not hot—water and a mild cleanser.

After washing, dry your feet carefully, particularly between the toes. Excess moisture between the toes can contribute to skin problems.

If you have reduced sensation, test the water temperature with your elbow or a thermometer rather than relying only on your feet to judge whether the water is too hot.

3. Moisturise Dry Skin

Dry, cracked skin can become an entry point for bacteria.

Apply a suitable moisturiser to dry areas of the feet to help maintain the skin barrier. However, avoid applying moisturiser between the toes unless specifically advised by your healthcare professional, because this area should generally be kept dry.

4. Wear Properly Fitting Shoes

Your footwear should protect your feet without creating excessive pressure or friction.

Choose shoes that:

• Fit comfortably
• Provide enough room for your toes
• Do not pinch or rub
• Have adequate cushioning and support
• Protect the entire foot

If you have a foot deformity or are at high risk of ulceration, your doctor may recommend specialized or therapeutic footwear.

The IWGDF emphasizes appropriate footwear as an important component of diabetic foot-ulcer prevention.

5. Check Your Shoes Before Wearing Them

Before putting on your shoes, inspect the inside.

Look for:

• Small stones
• Rough areas
• Torn lining
• Foreign objects
• Uneven surfaces

This is especially important if you have reduced sensation and may not feel an object rubbing against your foot.

6. Wear Clean, Comfortable Socks

Choose socks that fit comfortably and do not create excessive pressure.

Avoid socks that are extremely tight around the ankle or leave deep marks on the skin.

If your feet tend to sweat, changing socks regularly can help keep them comfortable and dry.

7. Trim Toenails Carefully

Toenails should generally be trimmed carefully and straight across rather than cut deeply into the corners.

Do not cut the skin around the nail.

If your nails are thick, difficult to reach, deformed or you have reduced sensation, ask a healthcare professional for advice rather than attempting difficult nail care yourself.

8. Protect Your Feet From Extreme Temperatures

Reduced sensation can make it difficult to recognize a burn or cold injury.

Avoid placing your feet directly against:

• Hot-water bottles
• Heating pads
• Room heaters
• Very hot surfaces
• Ice packs

If you have reduced sensation, be particularly cautious with bath and shower temperatures.

9. Attend Regular Foot Examinations

Daily self-checks do not replace professional assessment.

Your healthcare team can evaluate sensation, circulation, skin condition, foot structure and other risk factors.

The frequency of professional assessment depends on your individual risk. People with neuropathy, peripheral artery disease, previous ulcers, amputation or certain foot deformities may require more frequent monitoring.

10. Manage Your Diabetes and Other Risk Factors

Foot care is not separate from overall diabetes management.

Work with your healthcare team to manage:

• Blood glucose
• Blood pressure
• Cholesterol
• Weight and overall metabolic health
• Smoking

Good diabetes management can help reduce the risk of complications, while stopping smoking is particularly important because smoking can reduce blood flow to the feet.

Diabetic Foot Care: What You Should Not Do

1. Don’t Walk Barefoot

Avoid walking barefoot, even indoors, if you have diabetes-related loss of sensation or other foot-ulcer risk factors.

You could step on a sharp object, develop a blister or injure your skin without realizing it.

The IWGDF specifically recommends avoiding barefoot walking and walking in socks only or thin-soled slippers for people at risk of diabetic foot problems.

2. Don’t Ignore a Small Cut or Blister

A small wound may appear harmless, but diabetes can interfere with normal healing.

Do not simply cover a wound and forget about it.

Inspect it regularly and seek professional advice if it is not healing normally or if you notice redness, swelling, drainage or other concerning changes.

3. Don’t Cut Your Own Calluses Aggressively

Calluses often develop because of repeated pressure or friction.

Do not cut them with:

• Razor blades
• Scissors
• Knives
• Other sharp instruments

In addition, avoid chemical callus removers unless specifically recommended by a healthcare professional.

The IWGDF recommends avoiding chemical agents or plasters for removing calluses in people at risk of diabetic foot ulceration.

4. Don’t Wear Tight or Uncomfortable Shoes

Footwear that repeatedly rubs or presses against one area can contribute to blisters, calluses and tissue damage.

Do not assume that you simply need to “break in” a shoe if it causes persistent rubbing or pain.

Check your feet after wearing new footwear, particularly during the initial period.

5. Don’t Soak Your Feet for Long Periods

Long periods of soaking can dry or weaken the skin.

Instead, wash your feet gently and dry them thoroughly.

6. Don’t Use Very Hot Water

If sensation is reduced, you may not recognize that water is dangerously hot.

Always check the temperature before placing your feet in a bath or basin.

7. Don’t Use Heating Pads Directly on Your Feet

A heating pad or hot-water bottle can cause a burn that may go unnoticed when sensation is reduced.

Use safer methods to stay warm and follow your healthcare professional’s advice if your feet are frequently cold.

8. Don’t Wait for Pain

This is one of the most important diabetic foot care rules.

Pain is not a reliable warning sign when diabetic neuropathy has reduced sensation.

A serious wound or infection may sometimes develop with little or no pain.

Instead of waiting for pain, pay attention to visible changes such as redness, swelling, drainage, colour changes, wounds or areas of unusual warmth.

Warning Signs You Should Never Ignore

Contact a healthcare professional if you notice:

• A cut or open wound
• A blister that is not healing
• Increasing redness
• Swelling
• Pus or other drainage
• Bad odour
• A new area of warmth
• Skin colour changes
• A worsening callus
• Black or darkened tissue
• Increasing pain or tenderness
• A wound that becomes deeper or larger
• Changes in the shape of the foot

Some symptoms require more urgent assessment.

Seek prompt medical attention if you develop rapidly spreading redness or swelling, significant drainage, black tissue, fever, chills, or a deep or rapidly worsening wound.

Can a Small Foot Injury Become a Diabetic Foot Ulcer?

Yes.

A diabetic foot ulcer can begin with something that appears minor—a blister, small cut, pressure point or crack in the skin.

If the person has reduced sensation, they may continue walking on the affected area. Repeated pressure can prevent the tissue from recovering. If circulation is also impaired or infection develops, the wound may become increasingly difficult to heal.

This is why prevention and early intervention are so important.

What Should You Do If You Find a Foot Wound?

If you discover a wound:

1. Do not ignore it.
2. Avoid unnecessary pressure on the affected area.
3. Keep the area appropriately protected and clean.
4. Do not cut or manipulate the wound yourself.
5. Contact your healthcare professional for appropriate assessment.
6. Follow recommended wound-care and offloading instructions.

If the wound shows signs of infection or is becoming worse, do not delay medical evaluation.

What Is Offloading and Why Is It Important?

Offloading means reducing pressure and mechanical stress on an area of the foot that is at risk or already has an ulcer.

For example, a wound on the sole of the foot may continue to experience pressure every time you walk. Simply dressing the wound may not address the mechanical cause.

Depending on the location and severity of the problem, a healthcare professional may recommend specialized footwear, an offloading device or another method of reducing pressure.

Offloading is an important part of treatment for many diabetes-related foot ulcers.

When Does a Diabetic Foot Problem Need Specialist Care?

Not every diabetic foot problem requires surgery.

However, specialist evaluation may be necessary when there is:

• A persistent or non-healing ulcer
• Significant tissue loss
• Deep infection
• Exposed tendon or bone
• Severe foot deformity
• Poor blood supply
• Recurrent ulcers
• Extensive wound breakdown

Treatment may involve several specialists depending on the underlying problem.

A multidisciplinary approach can include diabetes management, wound care, pressure offloading, vascular assessment, infection treatment, orthopedic or surgical care, and reconstructive surgery when necessary.

Role of Reconstructive Surgery in Complex Diabetic Foot Wounds

Some severe diabetic foot wounds result in significant loss of skin and soft tissue.

Once infection and other underlying problems have been appropriately addressed, some wounds may require reconstruction to provide durable tissue coverage.

Depending on the wound and the patient’s overall condition, reconstructive options may include:

• Skin grafting
• Local tissue rearrangement
• Regional flap procedures
• Microsurgical free-flap reconstruction in selected complex cases

The goal is not simply to close the wound. A successful treatment plan must also consider blood supply, infection, pressure, tissue quality and the underlying cause of the wound.

Reconstructive surgery may therefore be one component of a broader limb-preservation strategy rather than a standalone treatment.

A Simple Daily Diabetic Foot Care Routine

A practical routine can make foot care easier to maintain.

Morning

• Choose clean, comfortable socks.
• Check that your shoes fit properly.
• Inspect the inside of your shoes before wearing them.

During the day

• Avoid walking barefoot.
• Pay attention to rubbing or pressure from footwear.
• Avoid exposing your feet to extreme heat or cold.

Evening

• Remove your shoes and inspect both feet.
• Check the soles and spaces between your toes.
• Look for cuts, blisters, redness, swelling or colour changes.
• Wash and dry your feet carefully.
• Apply moisturiser to dry areas, avoiding the spaces between the toes.

This routine takes only a few minutes but can help you notice problems before they become more difficult to treat.

Frequently Asked Questions About Diabetic Foot Care

How often should I check my feet if I have diabetes?

Checking your feet every day is recommended, particularly if you have neuropathy or other risk factors for foot complications.

Can I walk barefoot at home if I have diabetes?

If you have reduced sensation or are at increased risk of foot ulceration, it is safer to avoid walking barefoot, including indoors.

Should I use moisturiser on diabetic feet?

Moisturiser can help manage dry skin, but it should generally not be applied between the toes because that area should remain dry.

Can I cut my own calluses?

Avoid cutting calluses yourself with sharp instruments. Chemical callus removers should also not be used unless recommended by a healthcare professional.

Is a painless wound on a diabetic foot serious?

It can be. Neuropathy may reduce sensation and mask pain. A painless wound still requires attention, particularly if it is not healing or shows signs of infection.

When should I see a doctor for a diabetic foot problem?

Seek medical advice for any open wound, persistent blister, redness, swelling, drainage, colour change or other unusual foot change. Urgent assessment is particularly important for black tissue, rapidly spreading redness or swelling, fever, significant drainage or a deep wound.

Takeaway: Prevention Starts With Daily Foot Care

For clinical information, visit our diabetic foot treatment page, review lower-limb reconstruction, or contact the clinic.

Diabetic foot problems are not always preventable, but many risks can be reduced through consistent foot care. Checking your feet every day, wearing appropriate footwear, protecting your skin, avoiding barefoot walking and seeking early medical attention for wounds can help reduce the risk of serious complications.

Do not wait for a foot problem to become painful before taking action. If you notice a wound that is not healing, signs of infection, significant tissue damage or another concerning change, seek professional evaluation promptly.

For complex wounds requiring specialist management, including selected cases where tissue reconstruction is needed, Dr. Vinay Jacob and the reconstructive surgery team at The Plastic Surgeons can assess the wound and determine whether reconstructive treatment is appropriate as part of multidisciplinary care.
