Why Diabetes and Foot Health Are Inseparably Linked
Diabetes affects the feet in two important ways. First, elevated blood sugar over time can damage the peripheral nerves — a condition known as diabetic neuropathy — leading to reduced or absent sensation in the feet. Second, diabetes impairs circulation, slowing the delivery of oxygen and nutrients that the body needs to heal wounds.
This combination is dangerous. A person with diabetic neuropathy may not feel a blister, cut, or foreign object in their shoe. Without prompt attention, small wounds can become infected, and infections can spread to the bone: a condition called osteomyelitis. In severe cases, this can result in amputation.
According to the American Diabetes Association, diabetes is the leading cause of non-traumatic lower-limb amputations in the United States. Most of these amputations are preventable with proper care.
8 Steps for a Daily Self-Check Routine
The following steps form the foundation of proactive diabetic foot care at home:
Step 1: Inspect Your Feet Every Day
Use a mirror to check the bottoms of your feet, or ask someone to help. Look for:
- Cuts, scrapes, blisters, or sores
- Redness, swelling, or warm spots
- Cracks or dryness in the skin
- Nail changes or signs of infection
Do not skip this step — even on days when your feet feel fine.
Step 2: Wash Your Feet Daily
Use lukewarm (not hot) water and mild soap. Always test water temperature with your elbow or a thermometer, since neuropathy can impair your ability to detect heat accurately. Dry thoroughly, especially between the toes, where moisture can lead to fungal infections.
Step 3: Moisturize — But Not Between the Toes
Apply a gentle, fragrance-free moisturizer to the tops and bottoms of your feet to prevent cracking. Avoid applying lotion between the toes, as this can create a moist environment that promotes fungal growth.
Step 4: Trim Nails Carefully
Cut toenails straight across and file the edges smooth. Avoid cutting too short or rounding the corners, which can lead to ingrown toenails. If you have neuropathy, poor circulation, or vision problems, have a podiatrist handle nail care.
Step 5: Choose and Inspect Footwear Daily
Proper footwear is one of the most important protective tools for someone with diabetes. Key tips include:
- Wear well-fitting, supportive shoes with a wide toe box
- Always wear socks — preferably moisture-wicking, seamless diabetic socks
- Inspect the inside of your shoes before putting them on every time to check for pebbles, torn linings, or other irritants
- Never walk barefoot, even indoors
NIFAS offers a diabetic foot shoe program to help patients find appropriate footwear.
Step 6: Keep Blood Sugar in Control
Managing blood glucose levels is the most powerful long-term protection for your feet. Consistently high blood sugar accelerates nerve damage and circulation problems. Work with your primary care provider or endocrinologist to keep your numbers within a healthy range.
Step 7: Stay Active — Within Safe Limits
Regular low-impact exercise like walking and swimming improves circulation and supports healthy blood sugar levels. Talk to your healthcare team about an appropriate exercise plan. Avoid activities that put excessive pressure on the feet without proper footwear and supervision.
Step 8: Schedule Regular Diabetic Foot Exams
Even if your feet feel fine, a professional foot exam is essential at least once a year — and more frequently if you have neuropathy, poor circulation, or a history of foot problems. At Northern Illinois Foot & Ankle Specialists, diabetic foot exams include a thorough assessment of sensation, circulation, skin integrity, and nail health.
Proper Footwear and Hygiene: Why They Matter So Much
Footwear and daily hygiene may seem basic, but they are the front line of defense in diabetic foot care.
Footwear mistakes that can cause harm:
- Shoes that are too tight or too loose (causing friction and pressure points)
- Open-toed shoes or sandals without adequate protection
- Worn-out shoes with collapsed support
- New shoes worn too long before breaking them in
Hygiene mistakes to avoid:
- Soaking feet (which can macerate and break down skin integrity)
- Using harsh products like alcohol or hydrogen peroxide on open wounds
- Ignoring minor cuts or blisters
- Skipping the daily foot inspection
Warning Signs of Complications: When to See a Specialist
Seek prompt care from a podiatrist if you notice any of the following:
- A wound, ulcer, or blister that does not begin healing within a few days
- Increasing redness, warmth, or swelling around a wound
- Drainage, pus, or a foul odor from a wound
- Numbness, tingling, or burning in your feet
- A blue, black, or dramatically pale area of skin
- Fever along with foot pain or swelling
- A new or worsening change in the shape of your foot
These symptoms can indicate infection, poor circulation, or other complications that require immediate attention. Do not wait to see if they resolve on their own.

Frequently Asked Questions
Why is diabetes foot care so important?
Diabetes damages nerves and impairs circulation in the feet, making it harder to feel injuries and harder for wounds to heal. Without proper care, minor problems can escalate into serious infections or, in extreme cases, require amputation. Daily foot care and regular professional exams are essential for prevention.
What is a good daily self-check routine for diabetic feet?
A daily routine should include visually inspecting your feet for cuts, sores, redness, or swelling; washing with lukewarm water; drying thoroughly (especially between the toes); moisturizing the skin; and checking your shoes before putting them on. Report any abnormalities to your podiatrist promptly.
What are the warning signs of diabetic foot complications?
Warning signs include wounds or ulcers that do not heal, increasing redness or warmth, pus or drainage, numbness or tingling, color changes in the skin, and fever accompanied by foot symptoms. These require prompt professional evaluation.
How often should someone with diabetes see a podiatrist?
Most people with diabetes should have a professional foot exam at least once a year. Those with neuropathy, poor circulation, or a history of foot ulcers may need more frequent visits — sometimes every 1–3 months.
What kind of shoes should someone with diabetes wear?
People with diabetes should wear well-fitting, supportive shoes with a wide, rounded toe box, cushioned insoles, and no seams in pressure areas. Specialized diabetic footwear is available and may be covered by insurance. Always wear socks and never go barefoot.
