Feet are one of the most important — and most overlooked — parts of diabetes care. High blood sugar over time can reduce sensation and blood flow, so a small problem can become serious before you feel it. The good news: a simple daily routine prevents the vast majority of issues.
Why diabetes affects the feet
Two long-term effects of high blood sugar meet in the feet: nerve damage (neuropathy), which reduces the ability to feel pain, heat or injury, and reduced circulation, which slows healing. Together they mean a blister, cut or rub can go unnoticed and heal poorly. Learn more in our guide to diabetes complications.
Your daily 2-minute foot check
- Look at the tops, soles and between the toes — use a mirror or ask for help for the soles
- Feel for warm spots, swelling, or hard skin
- Watch for cuts, blisters, redness, cracks, ingrown nails, or color changes
- Act early — anything that isn’t improving in a day or two, contact your care team
Everyday habits that protect your feet
- Wash daily in lukewarm (not hot) water; dry well, especially between the toes
- Moisturize dry skin — but not between the toes (moisture there invites infection)
- Never go barefoot, even indoors; check inside shoes for stones or rough seams before wearing
- Choose well-fitting shoes with room for the toes; break in new shoes gradually
- Trim nails straight across; if you can’t see or reach well, have a professional do it
- Keep blood sugar and circulation healthy — activity helps blood flow; don’t smoke
What NOT to do
- Don’t use hot water bottles or heating pads on numb feet (burn risk you may not feel)
- Don’t remove corns or calluses with blades or strong chemicals — see a professional
- Don’t ignore a wound “to see if it heals” — early care prevents serious problems
When to see a professional promptly
Contact your doctor or podiatrist quickly for a wound that won’t heal, spreading redness or warmth, pus, a foul smell, or any black tissue. These can signal infection that needs fast treatment. Everyone with diabetes should also have a professional foot exam at least once a year.
- Numb feet are vulnerable feet — check yours every day.
- Never barefoot; well-fitting shoes; dry between the toes.
- Any non-healing wound = prompt professional care.
- Yearly professional foot exam for everyone with diabetes.
Frequently asked questions
How do I know if I have nerve damage?
Tingling, burning, or numbness in the feet are common signs. A provider can test sensation quickly — ask at your next visit.
Are special “diabetic socks” worth it?
Seamless, non-binding socks can help some people avoid rubbing and pressure. They’re optional, not essential — comfort and fit matter most.
Can foot problems be reversed?
Good blood sugar control can slow or stabilize nerve damage; established damage is usually managed rather than reversed. Prevention is key.
