If you live with diabetes, caring for your feet isn’t just about comfort — it’s about preventing serious complications that can affect your health and independence. One of the most common issues people with diabetes face is foot calluses — thickened, hardened areas of skin that can lead to infections or ulcers if not managed carefully.

In this comprehensive guide, we’ll explain why diabetic foot calluses form, how to manage them safely, and what treatments — both at home and with your podiatrist — are most effective. Whether you’re newly diagnosed or have been managing diabetes for years, understanding how to care for your feet is essential for maintaining mobility and avoiding complications.

What Are Diabetic Foot Calluses?

Calluses are areas of thick, dry skin that form in response to pressure or friction. On the feet, they commonly develop on weight-bearing areas like the heels, the ball of the foot, or over bony deformities like bunions or hammertoes.

For people with diabetes, calluses are more than just a cosmetic concern. They can:

• Increase localized pressure

• Mask developing wounds underneath

• Crack and open the door to infection

• Lead to ulcers, especially in those with neuropathy or poor circulation

Because diabetes can reduce sensation in the feet (a condition called peripheral neuropathy), calluses may go unnoticed until they become a bigger problem. That’s why proactive care is so important.

What Causes Calluses in People With Diabetes?

The root cause of most foot calluses is excessive pressure. In people with diabetes, this pressure is often magnified by other risk factors:

1. Peripheral Neuropathy

Nerve damage reduces the foot’s ability to sense irritation. Without feedback from pain or discomfort, a person may continue walking in a way that adds pressure to one spot — allowing a callus to build unnoticed.

2. Poor Circulation (Peripheral Artery Disease)

Reduced blood flow slows healing and thins the skin, making it more vulnerable to breakdown under calluses.

3. Foot Deformities

Conditions like hammertoes, bunions, or high arches can create uneven pressure points that lead to repeated friction and callus formation.

4. Improper Footwear

Shoes that are too tight, too loose, or lack support can cause abnormal pressure patterns — especially when combined with neuropathy.

5. Obesity

Excess body weight increases stress on the feet and can accelerate callus formation, especially in areas that already bear pressure.

Why You Should Never Ignore a Callus

Many people are tempted to self-treat foot calluses with over-the-counter tools or products — or worse, ignore them entirely.

But for people with diabetes, even a simple callus can turn into a serious wound.

• Calluses can disguise ulcers forming underneath.

• Cracked calluses can introduce bacteria into deeper layers of skin.

• Infections from untreated ulcers can lead to hospitalizations — and in some cases, amputation.

Staying ahead of callus development is a crucial part of diabetic foot care. The goal isn’t just removing them — it’s preventing them from forming in the first place.

Home Care: What You Can Do Safely

If you have diabetes, foot care begins at home — but it must be done carefully and with professional guidance.

Here are safe, daily practices to help reduce your risk:

1. Keep Feet Clean and Dry

Wash your feet daily with mild soap and lukewarm water. Gently pat them dry — especially between the toes. Moisture trapped between toes can lead to fungal infections.

2. Moisturize (But Avoid Between the Toes)

Dry skin increases the risk of cracks. Use a diabetic-friendly cream to hydrate your feet, avoiding fragranced or petroleum-based products. Don’t apply lotion between your toes.

3. Wear Supportive, Properly Fitted Shoes

Avoid high heels, narrow toe boxes, or shoes without arch support. Opt for footwear designed for people with diabetes — wide, cushioned, and breathable.

4. Use Protective Padding

If you have a callus-prone area, use non-medicated cushioning pads to reduce pressure. Avoid medicated corn or callus removers containing salicylic acid. Salicylic acid is contraindicated for diabetic skin because it can break down healthy skin and lead to ulceration.

5. Inspect Feet Daily

Check for any signs of redness, swelling, skin breakdown, or pain. Use a mirror or ask for help if you can’t see the bottoms of your feet.

When to See a Podiatrist

Even with good home care, regular visits to a podiatrist are essential. They can help identify pressure points early, safely remove calluses, and provide custom recommendations.

Professional treatments may include:

1. Debridement

Your podiatrist can gently remove the thickened skin using sterile tools — reducing pressure and helping prevent skin breakdown.

2. Custom Orthotics

These inserts are tailored to your feet and help redistribute pressure more evenly, reducing the chance of callus formation.

3. Offloading Devices

Special shoes or boots can temporarily shift weight off callused or ulcerated areas to promote healing.

4. Wound Care

If an ulcer has developed under or around a callus, proper wound care is crucial — including dressings, debridement, and infection prevention.

A Targeted Solution: SkinIntegra Rapid Crack Repair Cream

SkinIntegra’s patented Rapid Crack Repair Cream was developed specifically for diabetic skin. Its formula is precisely calibrated to address the two key challenges of managing diabetic foot calluses: exfoliating hardened buildup and restoring a compromised skin barrier.

What Makes SkinIntegra Different?

• Exfoliating and moisturizing ingredients

• Urea (25%): A powerful yet skin-friendly keratolytic that softens and breaks down thickened skin

• Lactic acid: Gently loosens and exfoliates dry surface layers

• Hyaluronic acid: Attracts and retains moisture to improve hydration and texture

• These ingredients work synergistically to reduce build-up and help prepare the skin for barrier repair.

• Barrier-restoring ingredients

• Ceramides

• Essential fatty acids

• Natural plant oils
  These components mimic the natural lipids of healthy skin, helping rebuild the barrier, reduce transepidermal water loss, and protect against further breakdown.

SkinIntegra’s formula is also:

• Free from fragrances, dyes, parabens, phthalates, petroleum derivatives, and other known irritants

• Safe for daily use on diabetic skin

• Clinically tested: In a study, 100% of participants with diabetes and dry, cracked feet showed improvement after just one day

Best Practices for Prevention

Preventing calluses is more effective — and safer — than treating them once they’ve formed. Here’s how to protect your feet every day:

When to Seek Immediate Medical Help

Contact a podiatrist or healthcare provider promptly if you notice:

• Redness, swelling, or pus near a callus

• A wound that does not heal within 7 days

• Increased pain, burning, or numbness

• Warmth or discoloration in the foot

• Sudden changes in sensation or appearance

Early treatment helps avoid serious outcomes like infection, hospitalization, or amputation.

Frequently Asked Questions (FAQ)

What’s the difference between a callus and a corn?

Calluses are large, thick areas of skin that usually develop on the soles of the feet. Corns are smaller, often harder, and appear on or between the toes. Both result from pressure or friction.

Is it safe to use a pumice stone?

Only under the guidance of your healthcare provider. Even minor abrasions can lead to serious wounds in people with diabetes.

Can diabetic calluses go away on their own?

They may reduce with proper pressure relief, moisturizing, and improved footwear — but it’s important to have them monitored professionally.

Do calluses always lead to ulcers?

No, but they are a known risk factor. Calluses can hide ulcers beneath them or crack and lead to infection.

Why should people with diabetes avoid salicylic acid?

Salicylic acid can damage healthy tissue, especially in people with impaired healing. It increases the risk of skin breakdown and ulcers in diabetic feet.

Take Control of Your Foot Health

Diabetic foot calluses can be safely managed — and often prevented — with a combination of self-care, smart products, and professional support. By staying vigilant, using the right treatments, and partnering with your podiatrist, you can protect your feet and maintain your mobility.

Make foot care a non-negotiable part of your diabetes management plan.
