Diabetic Foot Care: A Simple Daily Checklist That Helps Prevent Serious Problems

If you have diabetes, your feet need more attention than most people give them. That's not a criticism. Over time, high blood sugar can damage nerves (neuropathy) and reduce circulation. Your feet may not feel an injury the way they should, and a small wound may not heal the way it used to. Nerve damage is common: a Cochrane review notes that it affects 4 to 5 in 10 people after ten years with diabetes (Callaghan and colleagues, 2012).

Here's the good news. A few minutes of daily care helps you catch problems while they're still small. Treating a problem early can often keep it from getting worse (Frykberg, 2002).

The Daily Foot Check

Check both feet every day, ideally after a shower or before bed. Look at every surface of both feet.

• Between each toe. Look for moisture, peeling or cracks, which can let fungus and bacteria in.
• The sole of each foot. Use a mirror or your phone's camera if you can't see the bottom easily. Look for redness, swelling, blisters, cuts or areas that have changed color.
• Around the nails. Check for ingrown edges, thickening, color changes or any drainage.
• The tops, sides and heels. Look for new calluses, bumps, cracks or skin changes.

Doctors call early problems like these pre-ulcer signs. Treating them lowers the risk of a foot ulcer (Armstrong and colleagues, 2023). A blister you find today can be protected and watched. The same blister, unnoticed for a week on a numb foot, can turn into an infected wound.

Also feel both feet with the back of your hand. A spot that's warmer than the same spot on the other foot can be an early sign of trouble. For some higher-risk patients, the international guideline suggests tracking foot temperature (Bus and colleagues, 2024).

After the Shower

Wash your feet daily in warm, not hot, water. Test the water with your elbow or a thermometer first, because numb feet may not feel a burn. Skip long soaks. In a study of people with diabetes, washing the feet every day was linked with less athlete's foot, although the result was borderline (Takehara and colleagues, 2025).

Dry your feet well, especially between the toes. Then rub a gentle, fragrance-free moisturizer into the tops and soles, but not between the toes. Nerve damage can reduce sweating, and the dry skin that results can crack and turn into an ulcer (Oe and colleagues, 2025). That same review found that moisturizers, including urea creams, can help relieve dry feet.

Before You Put On Shoes

Run your hand inside each shoe before you put it on. Feel for pebbles, bunched-up insoles, rough seams or anything that could press on your foot. With less feeling in your feet, you might not notice something rubbing until it has already made a blister or a wound.

Check your socks too. Wear clean, dry socks with smooth seams that don't sit over bony spots, and change them if they get damp. Socks designed for people with diabetes are made this way.

Shoes That Protect

Good shoes are one of your main defenses. The international guideline advises people at risk not to walk without proper foot protection (Bus and colleagues, 2024). Look for shoes with these features.

• A wide, deep toe box that doesn't squeeze any part of the foot
• A firm, cushioned sole
• A smooth lining without rough seams or ridges
• Laces or hook-and-loop straps that hold the foot, instead of slip-ons
• Room for a custom orthotic, if you've been prescribed one

Don't walk barefoot, whether you're at home, at the beach or in the yard. Stepping on something sharp or hot is an easy way to start a wound when you can't fully feel your feet. Injury is one of the most common causes of diabetic foot ulcers (Frykberg, 2002).

If you're at moderate or high risk, the guideline recommends well-fitting therapeutic shoes (Bus and colleagues, 2024). In a 2023 review, shoes designed to take pressure off vulnerable spots lowered the rate of ulcers compared with usual care (Armstrong and colleagues, 2023).

Nail Care: What to Do and What to Avoid

Trim toenails straight across with clean clippers, and smooth sharp edges with a file. Don't round off or dig out the corners. Nail care habits and shoes are the most common factors behind ingrown toenails (Mayeaux and colleagues, 2019). If your nails are thick or hard to trim, or you have numbness, poor circulation or poor eyesight, have a health professional trim them. With diabetes, even a small nick next to the nail can get infected. More about ingrown toenail treatment.

Never use sharp tools to dig at nails or cut calluses. "Bathroom surgery" on a diabetic foot can turn a small problem into a wound. Calluses matter: in one study of people with nerve damage, an ulcer was far more likely to form under a callus (Murray and colleagues, 1996).

When to Call Us Immediately

Don't wait for your next scheduled visit if you notice any of the following.

• A cut, blister or sore that isn't clearly getting better
• Redness or warmth spreading from a wound
• Any drainage or unusual odor from a wound
• A new area of numbness or tingling
• A color change in part of your foot: darker, paler or bluish
• Sudden swelling in one foot without an obvious cause
• Pain in your calf or leg, especially on one side

These aren't wait-and-see situations. Prompt treatment can often keep a small problem from getting worse (Frykberg, 2002). If you have fever or chills along with a foot wound, get emergency care. The same goes for sudden swelling and pain in one leg with chest pain or trouble breathing.

Your Feet Carry You Through Life

Daily foot care for diabetes isn't complicated, but it takes consistency. Think of it like brushing your teeth: a small daily habit that heads off bigger problems. If something does come up, act early.

We see patients with diabetes for wound checks and yearly exams. For the warning signs of an ulcer, read diabetic foot ulcer warning signs.
