Diabetic Foot Care: Daily Foot Check & Winter Tips

Good diabetic foot care comes down to one habit that takes about two minutes: look at your feet every day, top and bottom and between the toes, and act fast when something changes. When diabetes has dulled the feeling in your feet or slowed the blood flow to them, a small blister can turn into an open sore before you ever feel it. Your eyes have to do the job your nerves used to do.

November is American Diabetes Month, and it is also the start of the hardest season for feet in New Jersey and the Hudson Valley. Radiators come on, boots come out, heels crack, and people with numb feet prop them in front of space heaters. Below you will find a daily foot check routine, the signs that mean call your doctor today, nail and skin care, socks and shoes, winter risks, and a short note on the Medicare shoe benefit.

The quick answer

• Check both feet every day, including the soles and between the toes.
• Call your doctor the same day for any open sore (even a painless one), redness or warmth, or a callus with dried blood in it.
• Never cut corns or calluses yourself. Trim nails straight across.
• No heating pads or hot water bottles on your feet, and keep them away from heaters.
• Moisturize cracked heels, but not between your toes.
• Medicare's therapeutic shoe benefit runs on a calendar year. If you qualify and have not used it for 2026, start before December 31.

Why small foot problems get dangerous with diabetes

Neuropathy: the warning system goes quiet

High blood sugar over time damages nerves, and the long nerves that run to your feet tend to go first. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) puts it plainly: you may not feel a pebble in your sock or a blister on your foot. Pain is supposed to make you stop and look. Without it, you keep walking on the injury.

Nerve damage also affects sweating, so skin on the feet gets dry and cracks, and it can slowly change the shape of your feet, creating new pressure points that shoes rub against.

PAD: injuries heal slowly

Diabetes can also narrow and harden the arteries in the legs and feet, which is peripheral artery disease (PAD). With less blood reaching the feet, cuts heal slowly and infections are harder to fight. The American Diabetes Association lists calf pain while walking that eases with rest as one warning sign. If you have been diagnosed with PAD, our article on arterial compression therapy for PAD covers one at-home option some doctors prescribe.

Put the two together and you get the classic chain: a shoe rubs, you don't feel it, a blister opens, poor blood flow keeps it from healing, and infection sets in. The CDC calls diabetes a major cause of toe, foot, and leg amputation, and notes that daily foot care could prevent many of them. The ADA goes further and says most amputations are preventable.

Your daily diabetic foot check

Pick a time you won't skip. Evening works for most people since your shoes and socks are coming off anyway, and NIDDK recommends checking each evening.

1. Sit in good light. A chair next to a lamp beats a dim bathroom.
2. Look at the tops, sides, and heels of both feet.
3. Check the soles. Use a hand mirror on the floor, a long-handled inspection mirror, or a phone photo. Or ask a family member to look.
4. Spread your toes and look between them for cracks, moisture, or peeling.
5. Feel for warm spots. One area that is clearly warmer than the same spot on the other foot is worth reporting.
6. Look at your socks. Blood or yellow drainage on a sock can show you a wound before you notice it on your skin.
7. Run a hand inside tomorrow's shoes for pebbles, torn lining, or loose seams.

What you find and what to do about it

Warning signs that mean call today

People with diabetes often wait on foot problems because nothing hurts. Don't. Going by NIDDK and ADA guidance, call your doctor or podiatrist the same day for a cut or blister that isn't healing after a few days, skin that is red, warm, or painful, a callus with dried blood inside, new swelling, drainage on your sock, or any open sore at all. The ADA is specific that every foot ulcer should be seen by a doctor right away, even if it doesn't hurt.

Nail and skin care do's and don'ts

• Do trim toenails after washing, straight across, and smooth the edges with an emery board.
• Don't dig into the corners. That is how ingrown nails start.
• Do let a podiatrist trim your nails if they are thick, yellow, curving into the skin, or hard for you to reach or see.
• Do wash feet daily in warm, not hot, water. Test it with your elbow, since numb feet can't judge temperature.
• Don't soak your feet. It dries and softens the skin.
• Do dry well between the toes, then moisturize tops and bottoms. The ADA suggests a thin layer of plain petroleum jelly or unscented cream.
• Don't put lotion between your toes. Trapped moisture there invites infection.
• Don't use razor blades, scissors, or drugstore corn and callus removers on your feet.

Socks and shoe fit

Choose socks that are seamless or flat-seamed, fit without leaving marks, and wick moisture (wool blends or synthetics rather than plain cotton). White or light colors make drainage easy to spot. Skip tight elastic tops. If someone has suggested compression socks, check your circulation first, since compression can be risky with significant PAD. Our article on who should not wear compression socks explains why.

For shoes:

• Wear shoes and socks all the time, including at home. NIDDK warns against going barefoot or in socks alone, even indoors.
• Get measured in person, since feet change over time. Leave about a thumbnail's width between your big toe and the end of the shoe.
• Look for a roomy toe box, smooth lining, and cushioned sole. Avoid pointed toes, heels, flip-flops, and plastic uppers.
• Break new shoes in a couple of hours at a time and check your feet afterward.

We go deeper on how diabetic shoes are built and fitted in The Science Behind the Shoe, so we won't repeat it here.

Winter risks for diabetic feet

Most winter foot injuries come from trying to stay warm.

Heating pads and hot water bottles. NIDDK, the CDC, and the ADA all say not to use them on your feet. With neuropathy you can get a real burn and not know until it blisters. Be just as careful with electric blankets and hot foot baths. Wear warm socks instead, including in bed.

Space heaters, radiators, fireplaces. Keep your feet well back from any heat source. Many older homes in North Jersey and Rockland County have cast iron radiators that get very hot, so watch where the ottoman sits.

Cold, wet feet. Slush soaks through shoes, and wet socks on poorly circulated skin is a bad combination. Numb toes also won't warn you about frostbite. Wear waterproof boots with enough depth for your inserts, change wet socks as soon as you get inside, and check your toes after time outdoors.

Dry, cracked heels. Indoor heat pulls moisture from skin, and a heel crack can split deep enough to bleed and get infected. Moisturize daily, wear closed-back shoes instead of open-back slippers, and show your podiatrist any crack that is deep or red around the edges.

Stiff winter boots. An hour of shoveling in a boot that pinches can leave a blister you won't notice until morning. Check your feet every time.

Where Medicare's therapeutic shoe benefit fits in

We cover the full process in our Diabetic Shoes and Medicare guide. The short version, per Medicare.gov and CMS therapeutic footwear guidance:

• Each calendar year: one pair of extra-depth shoes plus 3 pairs of inserts, or one pair of custom-molded shoes plus 2 more pairs of inserts.
• Who qualifies: people with diabetes plus a documented qualifying condition, such as neuropathy with callus formation, a history of ulcers or pre-ulcerative calluses, foot deformity, poor circulation, or a prior partial foot amputation.
• Certifying physician: the MD or DO managing your diabetes certifies that you meet the criteria and need the shoes. You need an in-person diabetes visit with that doctor within 6 months before delivery, and the certification must be signed within 3 months before delivery. A podiatrist can write the prescription.
• Cost: after the Part B deductible, generally 20% of the Medicare-approved amount when the supplier accepts assignment.

Use it before December 31. Because the benefit is per calendar year, an unused 2026 pair does not roll into 2027. Doctor paperwork can take a few weeks to come back, so November is a far better time to start than the week before the holidays. Medicare Advantage and other plans can have different rules, which is why MCB DME verifies your benefits before anything ships. You can see what we carry on our diabetic and orthopedic shoes page.

Common mistakes we see

• Checking only when something hurts. With neuropathy, pain is not a reliable alarm.
• Skipping the soles. Ulcers most often form on the ball of the foot and under the big toe, the spots people look at least.
• Bathroom surgery. Cutting a callus or ingrown nail at home is how many small problems become infections.
• Wearing worn-out inserts. Inserts compress with daily wear, which is part of why Medicare covers several pairs.
• Letting the shoe benefit lapse because no one started the paperwork.

FAQ

How often should I do a diabetic foot check?

Every day. Your doctor should also look at your feet at every visit, and the CDC recommends seeing a podiatrist at least once a year.

What if I can't see the bottoms of my feet?

Use a mirror on the floor, a long-handled inspection mirror, or your phone camera, or have a family member or caregiver look for you.

Can I use a heating pad on cold feet?

No. If you have any loss of feeling, a heating pad or hot water bottle can burn you without you noticing. Warm socks are the safe choice.

What should I put on cracked heels?

A thin layer of plain petroleum jelly or unscented cream after bathing, on the tops and bottoms of the feet but not between the toes. Have a podiatrist look at any crack that is deep, bleeding, or red.

Does the Medicare diabetic shoe benefit reset every year?

Yes. It is limited per calendar year, so if you qualify and haven't used it in 2026, it will not carry over to 2027.

Who has to certify that I need diabetic shoes?

An MD or DO who manages your diabetes. A podiatrist can prescribe, but the certification comes from the doctor treating your diabetes. We can help coordinate the paperwork with your doctors.

Key takeaways

• Neuropathy hides injuries and PAD slows healing, so small foot problems become serious fast.
• A two-minute daily check of tops, soles, and between the toes is the core of diabetic foot care.
• Any open sore, redness, warmth, or bloody callus means calling your doctor today.
• In winter, keep heat sources away from your feet and moisturize your heels.
• If you qualify for Medicare therapeutic shoes and haven't used the 2026 benefit, start now.
