Diabetic Foot Ulcer Prevention FAQ: Answers to the Most Asked Patient Questions
diabeteseducation
Common questions patients and families ask about preventing diabetic foot ulcers — from footwear to moisturizer to when to call the doctor.
Patients newly diagnosed with diabetes often receive a long list of foot-care rules with little context. This FAQ answers the questions clinicians hear most often in the exam room.
Can I ever walk barefoot at home?
No. Even indoors, a dropped needle, splinter, or Lego piece can cause an unnoticed puncture. Wear indoor shoes or padded slippers with a closed toe at all times.
Is it safe to soak my feet?
Soaking is discouraged. It macerates skin between the toes and raises infection risk. Wash briefly in lukewarm water and dry thoroughly.
How do I test water temperature if I can't feel it?
Use your elbow or a bath thermometer. Aim for under 95°F (35°C). Never trust your feet to gauge heat.
Where should I apply moisturizer — and where shouldn't I?
Apply to the tops, soles, and heels once daily. Never between the toes; trapped moisture promotes fungal infection and skin breakdown.
Are diabetic socks worth it?
Seamless, non-binding socks in a light color help. White or cream lets you spot blood or drainage from a wound you didn't feel.
Can I trim my own toenails?
If vision, dexterity, and sensation are intact, trim straight across. If any are impaired, see a podiatrist monthly. Self-trimming is a common route to ulcer.
When should I call my clinician?
Call within 24 hours for any blister, cut, redness, drainage, swelling, or new dark area — no matter how small.
What happens at a professional foot exam?
A full diabetic foot exam includes monofilament sensation testing, pulse checks, skin and nail inspection, and footwear review. Patients should have one at least three times per year as part of diabetic foot care.
