Types of Corns

Foot specialists classify corns into a few distinct types - each with its own location, look and handling. Knowing which type you have tells you a lot about its cause and care.

Hard corn (heloma durum)

The commonest type: a small, dense, dry patch with a hard central core, sitting on the tops or sides of toes - directly where bone meets shoe. Sharp pain on pressure. The classic tight-shoe corn.

Soft corn (heloma molle)

Forms BETWEEN toes - most often between the fourth and fifth toes, where two bones press together and sweat keeps the skin moist. Instead of drying hard, the thickened skin stays white, rubbery and macerated, with a sore center. Painful when toes are squeezed together. Narrow, pointed shoes are the usual cause, and keeping the area dry is part of the treatment.

Seed corn (heloma miliare)

Tiny corns - like embedded seeds or beads - usually in clusters on the sole or heel. Often more annoying than painful, and interestingly not always linked to pressure; dry skin plays a role.

Neurovascular corn

A long-standing corn in which nerves and tiny blood vessels have grown into the core - significantly more painful, may bleed when pared, and definitely a job for the professional rather than home blades.

The close cousin: callus

Not a corn type, but constantly confused with one: a broad, flat area of thickened skin (ball, heel, big-toe side) without a central core, usually painless - the body's sensible padding over a wide pressure zone. Calluses need the same pressure logic but rarely the same urgency.

Why the type matters

Hard corns respond well to footwear change plus soak-and-pumice care; soft corns need drying, toe separation and shoe width; seed corns need moisturizing; neurovascular corns need a professional. And anything you are not sure is a corn - especially in a child, where warts are far commoner - deserves a professional look before self-treatment.

One-line summary

Hard corns sit on toe tops, soft corns between toes, seed corns on soles, and neurovascular corns hurt the most - the type guides whether home care suffices or a professional should take over.
