How to Care for Diabetic Feet and Reduce Risk

A small blister, cracked heel or ingrowing toenail can become more serious when you have diabetes. Knowing how to care for diabetic feet is therefore not simply about keeping them comfortable. It is a practical part of protecting your mobility, independence and overall health.

Diabetes can affect circulation, sensation and the body’s ability to fight infection. This means an injury may go unnoticed, heal more slowly or deteriorate faster than expected. With a consistent routine and prompt professional advice when something changes, many diabetes-related foot complications can be prevented.

Why diabetes needs extra foot care

Over time, raised blood glucose can damage nerves in the feet and lower legs. This is known as peripheral neuropathy. You may experience tingling, burning or numbness, but some people lose sensation without any obvious warning. A stone in a shoe, a hot water bottle or a rubbing seam can then cause damage without causing pain.

Diabetes may also reduce blood flow to the feet. Good circulation supplies oxygen and nutrients needed for healthy skin and healing. When circulation is reduced, cuts and sores can take longer to repair and infection can be harder for the body to control.

Foot shape and pressure points matter too. Corns, callus, bunions, claw toes and changes in the way you walk can concentrate pressure beneath a particular area of the foot. If sensation is reduced, repeated pressure may lead to skin breakdown. This is why effective diabetic foot care combines skin and nail care with well-fitting footwear and, where needed, assessment of foot mechanics.

How to care for diabetic feet every day

A daily check is one of the most valuable habits you can establish. Choose a time that is easy to maintain, such as after washing or before bed. Look at the tops, soles, sides and heels of both feet, as well as between the toes. A mirror can help with the soles, or ask a family member or carer to assist if bending or eyesight makes checking difficult.

Look for cuts, blisters, redness, swelling, cracks, areas of hard skin, changes in colour, discharge, bruising and new pain. Also notice whether one foot feels hotter or colder than the other. Do not assume a problem is harmless because it does not hurt.

Wash your feet daily in warm, not hot, water and dry them carefully, particularly between the toes. Test the water with your elbow or a thermometer rather than your foot if you have reduced feeling. Soaking feet for prolonged periods is best avoided, as it can soften and weaken the skin.

Apply a moisturiser to dry skin on the tops and soles of your feet, but not between the toes. Moisture trapped between toes can encourage fungal infection and skin breakdown. If you have persistent cracking, scaling or itching, seek advice rather than treating it repeatedly without a clear diagnosis.

Toenails should be kept at a sensible length and cut straight across where possible, without digging down the sides. However, self-cutting is not right for everyone. If you cannot see or reach your feet safely, have thickened nails, poor circulation, reduced sensation or a history of ulceration, routine podiatry care is the safer option. Never use blades, corn plasters or strong chemical treatments to remove hard skin yourself.

Choose footwear that protects rather than rubs

Footwear is a daily protective device, not just a matter of style. Shoes should have enough depth and width for your toes, a fastening that keeps the foot secure, and a sole that provides cushioning and stability. The lining should be smooth, with no prominent seams that could rub.

Before putting shoes on, check inside them with your hand. Remove grit, check for damaged lining and make sure there is no object inside. This simple habit can prevent an avoidable pressure injury.

New shoes should be introduced gradually. Wear them indoors for short periods at first and inspect your feet afterwards for red marks or rubbing. A shoe that feels comfortable in the shop can still cause problems once you are walking for longer distances.

Avoid walking barefoot, including around the home, garden, swimming pool or beach. Slippers should fit securely and offer protection underfoot, rather than being loose or worn flat. Socks should be clean, changed daily and free from tight elastic or bulky seams. If swelling, toe deformity or recurrent rubbing makes shoe fitting difficult, a podiatrist can advise on suitable options and whether insoles or pressure-relieving modifications may help.

Keep pressure, circulation and glucose in view

Healthy foot care does not sit separately from diabetes management. Keeping blood glucose, blood pressure and cholesterol within the targets agreed with your diabetes team supports circulation, nerve health and healing. Stopping smoking is particularly valuable, as smoking can further impair blood flow.

Stay active in a way that is appropriate for your feet and general health. Walking, cycling and other exercise can support circulation and wellbeing, but activity should not be pushed through unexplained foot pain, swelling or skin damage. For people with altered sensation, checking feet before and after exercise is particularly sensible.

If you have a job that keeps you on your feet, or you are returning to running or sport, increased loading can reveal pressure areas that were previously manageable. Persistent callus, repeat blisters or pain under the forefoot are not just nuisances. They can indicate that footwear, movement pattern or foot mechanics need closer attention.

When to seek urgent help

Contact your GP, diabetes foot team, NHS 111 or urgent care service promptly if you notice a new open wound, ulcer, spreading redness, warmth, swelling, pus, bad smell or a sudden change in foot colour. A black, blue or unusually pale toe or foot requires urgent assessment. So does new pain in a numb foot, or a foot that becomes hot, red and swollen without an obvious injury.

A hot, swollen foot can occasionally be a sign of Charcot neuroarthropathy, a serious condition involving weakening of the bones and joints in the foot. It may be mistaken for a sprain or infection, especially if pain is limited by neuropathy. Avoid weight-bearing where possible and seek urgent medical advice.

Do not wait to see whether a cut, blister or suspected infection settles if you have diabetes. Early assessment is far easier than treating a wound once it has progressed.

Arrange regular professional foot reviews

Your diabetes care team should assess your feet at least annually, and more often if you are considered at increased risk. Risk is influenced by reduced sensation, poor circulation, previous ulceration or amputation, kidney disease, significant callus, foot deformity and difficulty managing foot care independently.

A podiatry appointment can identify concerns that are not always visible to you, including changes in sensation, circulation, nail health and areas of high pressure. At Footporium Podiatry, assessment can also consider biomechanics where repeated pressure, painful walking or structural changes are affecting how the foot loads during movement. The right plan may include routine care, footwear advice, pressure management or orthotic support, depending on the findings.

Diabetic foot care works best when it becomes ordinary: check, wash, dry, protect and act early when something looks different. If you are unsure whether a change needs attention, it is safer to have it assessed than to wait for pain to provide an answer.
