Athlete’s foot — also called tinea pedis — is a contagious fungal infection that affects the skin on the feet. It can also spread to the toenails and the hands. The fungal infection is called athlete’s foot because it’s commonly seen in athletes.
Fungal infections of the feet are usually characterized by redness, peeling, and/or itching. More likely what you are describing is just dead skin due to ineffective foot hygiene. Callus buildup is usually hard and is the foot’s way of protecting an area from rubbing or friction — as in improper shoe fit.
Cornmeal is a popular treatment for the toenail fungus condition. This is somewhat surprising as there has been no scientific research into its efficacy. However, there is plenty of anecdotal evidence to suggest that it is nevertheless an effective treatment.
A type of dermatitis, dyshidrotic eczema is much more common among women. Dyshidrotic eczema, also known as dyshidrosis or pompholyx, is a type of eczema that causes a blistering rash on the hands or feet, especially the fingers, palms, and soles.
Warts and Fungus. Warts are non-cancerous skin growths caused by a viral infection in the top layer of the skin. Viruses that cause warts are called human papilloma virus (HPV). Warts are usually skin-colored and feel rough to the touch, but they can be dark, flat and smooth.
Rarely, athlete’s foot can be caused by non-dermatophytes, like yeast . Athlete's foot is mildly contagious. It can be spread through direct contact with the infection and by skin particles left on towels, shoes, or floors. Walking barefoot may increase your chance of contracting athlete's foot. The risk of developing athlete's foot can also depend on your susceptibility.
Athlete’s foot occurs when the tinea fungus grows on the feet. You can catch the fungus through direct contact with an infected person, or by touching surfaces contaminated with the fungus. The fungus thrives in warm, moist environments. It’s commonly found in showers, on locker room floors, and around swimming pools.
