What do foot corns look like after removal?

Foot corns appear as hard skin when removed, though there remains a risk of recurrence, according to WebMD. Foot corns can be prevented by eliminating the friction and pressure that causes them.

Foot corns are hard patches of skin caused by exposure to consistent friction and pressure. Wearing comfortable shoes decreases the incidence of foot corn formation, notes WebMD. However, some patients may have abnormal foot structures or walking motions that lead to the development of foot corns. These patients can undergo surgery or use orthopedic shoe inserts to help correct the problem. Foot corns are distinguished from warts because the latter bleed when removed, while foot corns reveal more dead skin.
