Why corns and calluses form

MedlinePlus explains that corns and calluses are thick layers of skin caused by repeated pressure or friction. A corn is thickened skin on the top or side of a toe, most often from shoes that fit badly. A callus is thickened skin on the hands or soles of the feet, and can form over a bunion that rubs against a shoe.

The American Academy of Dermatology (AAD) says most corns and calluses go away once the friction or pressure causing them stops. Pads help by moving that pressure off the sore spot while you deal with the cause.

Types of pads

Details are from ZenToes, PediFix and a DailyMed drug label.

Non-medicated cushions

• Donut pads for corns. MedlinePlus suggests protecting a corn with a doughnut-shaped corn pad, sold at most drug stores. AAD says to surround a corn with donut-shaped adhesive pads to keep it from touching the shoe.
• Half-moon or U-shaped pads for calluses. AAD suggests cutting moleskin into two half-moon shapes and placing them around a callus. ZenToes says its U-shaped felt pads help protect calluses, bony areas and hot spots by absorbing friction and pressure, and sells them in 18, 24 and 48 count packs.
• Gel protectors. PediFix says its Visco-GEL Corn Protectors absorb pressure and friction, release mineral oil enriched with vitamin E to soften skin, and use a fabric sleeve to hold the gel without adhesive. It sells them in Small and Large.

For a sore toe that rubs all over, a full toe cap may work better; see our gel toe caps guide.

Medicated corn removers

Medicated corn pads are a drug, not just a cushion. A Leader medicated corn remover label on DailyMed lists salicylic acid 40% as the active ingredient. Its warnings say not to use it if you are a diabetic, if you have poor blood circulation, on irritated skin, or on any area that is infected or reddened, and to stop use and ask a doctor if discomfort persists.

Its directions are to wash and dry the area, cut the medicated patch to fit the corn, cover it with the supplied pad, remove it after 48 hours, and repeat every 48 hours as needed for up to 14 days. Follow the label of the exact product you buy, and keep it out of reach of children, as the label says.

Placing a pad well

• Clean and dry first. Adhesive sticks better to clean, dry skin.
• Center the opening. The hole or U should sit around the sore spot, so the pad takes the pressure instead of the corn.
• Check your shoe. A thick pad can make a tight shoe tighter. AAD suggests shopping for shoes at the end of the day, when feet may be slightly swollen, and avoiding shoes that are too tight or too loose.
• Trim toenails. AAD says long toenails can push toes against the shoe and add pressure.
• Moisturize. AAD suggests a daily cream with salicylic acid, ammonium lactate or urea to gradually soften hard skin. See our callus remover guide for filing safely.

Who should get care instead

• Diabetes or numbness. MedlinePlus says people with diabetes or nerve problems in the toes are prone to ulcers and infections and should check their feet carefully. AAD advises people with diabetes to see a board-certified dermatologist.
• Poor circulation. The medicated label says not to use salicylic acid pads with poor blood circulation.
• Signs of infection. MedlinePlus says to call your provider for continued pain, redness, warmth or drainage.
• Not improving. Call your provider if a corn or callus is not getting better with treatment, or if you are unsure what the hard spot is.

What to look for when you buy

Questions people ask

Do corn pads remove corns?

Cushion pads protect a corn; medicated pads with salicylic acid are made to remove it.

Can people with diabetes use medicated corn pads?

No. The label warns not to use them if you are a diabetic.

How long do you leave a medicated corn pad on?

One label says remove after 48 hours and repeat as needed for up to 14 days.

What pad is best for a callus?

AAD suggests half-moon moleskin around a callus; U-shaped felt pads work the same way.

Will the corn come back?

It can if the pressure continues. AAD says corns fade once friction or pressure stops.
