A daily foot check takes under five minutes and is the single highest-leverage habit for preventing diabetic foot complications in 2026.
TL;DR: Knowing how to check feet with diabetes means inspecting every surface — tops, soles, heels, and between the toes — every single day for cuts, blisters, redness, swelling, or changes in skin temperature. Neuropathy means you may feel nothing while damage is already underway. The diabetic foot care team at Family Foot & Leg Center, PA recommends booking a professional exam at least once a year, or immediately if you spot anything abnormal.
Why this matters
The CDC reports that roughly 15% of people with diabetes develop a foot ulcer during their lifetime, and approximately 80% of lower-limb amputations in the U.S. are preceded by a foot ulcer. Most of those ulcers start as something small — a blister from a new shoe, a tiny cut from a toenail — that went unnoticed because peripheral neuropathy had already dulled sensation. Catching problems at the blister stage is manageable. Catching them at the infected-wound stage is not.
In Southwest Florida, where sandal culture and warm pavement are year-round realities, the exposure risk is higher than in colder climates. Patients at Family Foot & Leg Center, PA's 9 locations across Naples, Fort Myers, Cape Coral, Estero, and Sarasota consistently report they "didn't feel anything" before a wound was already visible. Daily self-inspection closes that gap.
What you'll need
Before you start, gather:
- A well-lit room or a bright lamp positioned at foot level
- A handheld mirror (or a mirror mounted at floor level) to see your soles and heels
- A family member or caregiver who can check areas you physically cannot reach, especially if balance or flexibility is limited
- Clean hands and dry feet
- 3–5 minutes of uninterrupted time — same time each day builds the habit
If you have custom orthotics or prescribed diabetic footwear, remove them before the check and inspect them for debris, rough seams, or foreign objects before putting them back on.
The steps
Step 1 — Wash and dry your feet first
What it accomplishes: Clean feet let you see skin color, texture, and any lesions clearly. Drying thoroughly — especially between the toes — removes the moisture that fungal infections thrive on.
Why it matters: Athlete's foot and fungal toenail infections are common in people with diabetes and can crack the skin, creating an entry point for bacteria. In 2026, fungal foot infections remain one of the most underreported contributing factors to diabetic wounds.
Specific instructions: Wash with lukewarm water (test temperature with your elbow, not your foot — neuropathy can mask dangerously hot water). Dry gently with a soft towel, patting rather than rubbing. Use a separate clean cloth between each toe.
Expected outcome: Feet that are clean, dry, and visually clear of any residue that might hide a lesion.
Common mistake: Soaking feet. Prolonged soaking softens skin and increases infection risk. Keep washing time under 3 minutes.
Step 2 — Inspect the tops and sides of both feet
What it accomplishes: The tops and sides of the feet show signs of pressure from tight footwear — blisters, red marks, and the start of corns.
Why it matters: Shoes that fit poorly create repetitive friction. Neuropathy means you'll wear those shoes all day without discomfort signals, so the damage accumulates invisibly.
Specific instructions: Look at each foot in good light. Note any redness, swelling, or discoloration. Press gently on any red area — if the redness blanches and returns, that is early pressure damage. If it does not blanch, that tissue is already compromised.
Expected outcome: Identification of any pressure points or early blisters before they break open.
Common mistake: Checking only the sole. The top of the foot and the areas over bony prominences (the knuckles of the toes, the top of the arch) are just as vulnerable.
Step 3 — Use a mirror to check the soles and heels
What it accomplishes: The sole and heel are the highest-pressure areas during walking and the most common sites for diabetic ulcers, yet they are the hardest to see without a mirror.
Why it matters: Plantar ulcers (ulcers on the sole) account for the majority of diabetic foot ulcers treated in clinical settings. Heels crack under dry skin conditions, which are worsened by autonomic neuropathy reducing natural foot sweat.
Specific instructions: Place a mirror flat on the floor and stand over it, or hold a handheld mirror at an angle. Look at the ball of the foot, the arch, the heel, and beneath each toe. You are looking for cracks, calluses that have turned dark, blisters, open sores, or any area that looks different from yesterday.
Expected outcome: A full visual of the plantar surface in under 60 seconds.
Common mistake: Skipping this step when no pain is present. Pain is an unreliable signal in diabetic feet — the mirror check is non-negotiable regardless of how the foot feels.
Step 4 — Check between the toes
What it accomplishes: The interdigital spaces (between toes) are warm, moist, and prone to fungal infections, maceration, and small cuts that go undetected.
Why it matters: Soft tissue between the toes breaks down faster than elsewhere. A 2-millimeter cut between the third and fourth toe can track infection into deeper tissue if left untreated for even 48 hours.
Specific instructions: Gently spread each pair of toes apart and look at the skin directly. Check for peeling, white or soggy-looking skin, redness, odor, or any break in the skin. If you use a cotton swab, run it gently through the space — it will pick up any moisture that shouldn't be there.
Expected outcome: Confirmation that interdigital skin is intact, dry, and pink.
Common mistake: Applying lotion between the toes. Moisturizer belongs on heels and dry areas — not between toes, where it traps moisture.
Step 5 — Assess skin temperature and texture
What it accomplishes: Temperature differences between feet — or between areas of the same foot — are early signs of inflammation, Charcot foot, or infection. Texture changes flag dryness and callus formation before they crack.
Why it matters: A foot that is noticeably warmer than its pair by 4°F or more is a clinical red flag for Charcot foot, a serious complication in which bones weaken and fracture without pain. Family Foot & Leg Center, PA treats Charcot foot cases across its Southwest Florida locations, and early detection in 2026 still requires the same low-tech approach: touch.
Specific instructions: Run the back of your hand across the top and sole of each foot. Compare symmetry — left to right. Feel for unusual firmness or new callus buildup. If one foot is distinctly warmer, redder, or more swollen than the other, that is a same-day call to your podiatrist.
Expected outcome: Confidence that both feet feel similar in temperature and that skin texture is consistent with your known baseline.
Common mistake: Attributing warmth to "just being hot." Temperature asymmetry between feet is never normal.
Step 6 — Check toenails
What it accomplishes: Ingrown toenails and thickened fungal nails are infection entry points. Nails that are too long catch on socks and create micro-tears.
Why it matters: Podiatrists at Family Foot & Leg Center, PA see ingrown toenail infections in diabetic patients regularly — the majority trace back to improper trimming or shoes that were too tight.
Specific instructions: Nails should be trimmed straight across, not curved at the corners, and kept at or just above the end of the toe. If a nail is yellow, thick, or brittle, that is a fungal nail (onychomycosis) — do not attempt to trim it aggressively at home. If a nail edge is digging into the surrounding skin, do not probe it; call your podiatrist.
Expected outcome: Nails that are clean, trimmed, and showing no signs of ingrowth or fungal changes.
Common mistake: Cutting nails too short or rounding the corners, which increases the ingrown nail risk significantly.
Step 7 — Log anything new
What it accomplishes: A daily log — even a single note on your phone — creates a baseline. It helps you distinguish a change that appeared overnight from one that has been slowly progressing.
Why it matters: "I'm not sure when it started" is the most common answer podiatrists hear when a wound is found. A log eliminates that ambiguity and gives your care team a timeline.
Specific instructions: Note date, which foot, location on the foot, what you saw, and whether it looks better or worse than the previous day. A photo taken in the same lighting each day is even more useful. If anything is worse after 24 hours, call the office. Do not wait for a scheduled appointment.
Expected outcome: A running record that takes 20 seconds to update and materially improves your ability to catch deterioration early.
Common mistake: Thinking "I'll remember it" — you won't, and your podiatrist can't act on a vague description.
Troubleshooting
You can't reach your feet due to limited mobility.
Ask a family member or caregiver to perform the check. A long-handled mirror designed for foot inspection costs under $15 at most pharmacies. Some patients at Family Foot & Leg Center, PA's Southwest Florida clinics use a flexible phone holder to capture photos of their soles.
You found a small cut but it's not bleeding.
Clean gently with mild soap and water, apply a thin layer of antibiotic ointment, and cover with a non-stick bandage. Check it every 24 hours. If it shows no improvement — or shows any redness, warmth, or discharge — after 48 hours, call your podiatrist that day, not at your next scheduled visit.
Your skin is very dry and cracked, especially the heels.
Apply a urea-based heel cream (10%–25% urea concentration) to heels and dry areas after the foot check. Do not apply between toes. Severe heel fissures that bleed or are deep enough to snag a fingernail need professional treatment — diabetic foot care in Naples, FL includes wound treatment for heel fissures.
One foot looks swollen compared to the other.
This is not a "watch and wait" situation. Unilateral swelling in a diabetic foot in 2026 is treated as a potential Charcot foot or deep infection until proven otherwise. Call your podiatrist the same day.
You see a dark spot under a callus.
This is often a pre-ulcerative lesion — essentially a bruise under hardened skin that signals the tissue beneath is under excessive pressure. Do not trim the callus yourself. Book a same-day or next-day appointment.
You notice a new odor from one foot.
Odor combined with any wound, even a small one, is a sign of bacterial activity. This requires a professional evaluation within 24 hours.

FAQ
What's the best time of day to check your feet with diabetes?
Evening — after you've been on your feet all day — is optimal because any pressure damage from footwear will be most visible. The key is consistency: choose a time you'll actually do it daily and stick to it.
How often should a diabetic person check their feet?
Every single day, without exception. The American Diabetes Association recommends daily self-inspection as a standard of care. Missing even 2–3 days can allow a small wound to progress significantly.
Is foot pain a reliable sign of a problem in diabetic patients?
No. Peripheral neuropathy — present in roughly 50% of long-term diabetics — eliminates or blunts pain signals. A serious wound can exist with zero discomfort. Visual inspection is the only reliable method.
What does a diabetic foot ulcer look like in early stages?
Early ulcers often appear as a small break in the skin, sometimes surrounded by callus or a dark discolored area. The wound bed may look pink or red. There may be no pain and minimal drainage at first.
When should I call a podiatrist instead of watching at home?
Call same-day for: any wound that hasn't closed within 48 hours, swelling in one foot only, skin that is warm and red over a bony area, dark tissue at any wound edge, or odor from the foot. Do not wait for a scheduled appointment.
Can I use hydrogen peroxide on a diabetic foot wound?
No. Hydrogen peroxide damages the healing tissue and slows wound closure. Use mild soap and water to clean the wound, then apply an antibiotic ointment.
How does neuropathy affect daily foot checks?
Neuropathy removes the pain signal that normally alerts you to injury, meaning the check must be entirely visual and tactile (temperature, texture). You are replacing the sensation your nerves are no longer providing.
Do I need a doctor if my feet look fine?
Yes — a board-certified podiatrist should examine your feet at least once a year even when everything looks normal. A clinical exam detects circulation problems and early neuropathy that self-inspection cannot catch.
One last thing
Charcot foot — a condition in which bones in the foot fracture and collapse without causing pain — is seen more frequently in Florida than most patients expect, and it is almost always diagnosed late because there is no warning signal. The single earliest detectable sign is one foot being consistently warmer than the other, often by as little as 4°F. That temperature difference takes about 10 seconds to notice during a daily check. It is worth those 10 seconds.
