Causes of cracks in or between the toes
Many of the causes of cracks in or between the toes need warmth and moisture to grow and spread to create further issues. The feet are the perfect environment as most people wear shoes for the majority of the day, providing the ideal dark and warm space.
Inflammatory causes of cracks in or between the toes include the following.
- Infection: Cracks between the toes are most often caused by fungi that infect the skin (dermatophytes). The fungi enter the skin through small cracks or wounds and infect the topmost layer. Although fungi are the most common cause, other infectious pathogens such as bacteria can also infect the feet in a similar fashion and result in similar symptoms.
- Systemic disease: Conditions that weaken the immune system, whether from serious illness or long-term medication use, can put the body at risk for contracting infections and other inflammatory diseases. An individual with a weakened immune system cannot mount an appropriate response to pathogens. If the feet or toes become infected, cracks or skin breakdown may persist.
Dermatologic causes of cracks in or between the toes include the following.
- Primary: Primary dermatologic causes refer to cutaneous conditions that are the result of inherent problems with the skin and its components. Many of these conditions can affect the feet and cause cracks and dryness in the skin.
- Secondary: Secondary dermatologic conditions that result in cracks in or between the toes can occur due to secondary causes such as weather and poor moisturizer that results in dryness.
Environmental causes of cracks in or between the toes include the following.
- Irritation: Many substances can irritate the skin and cause rashes, redness, and cracking of the skin. This is known as dermatitis. Products such as heavily scented soaps, lotions, and even some types of jewelry around the toes can be very irritating and cause damage to the toes due to allergic or sensitivity reactions.
- Poor hygiene: Proper hygiene is essential in maintaining foot health. Regularly washing the feet with mild soap and water and adequately drying the feet after showering or exposure to water is important in keeping fungi and bacteria away.

Athlete's foot (tinea pedis)
Athlete's foot is a common fungal infection of the feet and/or toes. Warm, moist environments and community showering are common causes of this type of infection.
Top Symptoms: foot redness, foot/toe itch, foot skin changes, spontaneous foot pain, peeling between the toes
Symptoms that always occur with athlete's foot (tinea pedis): foot redness
Symptoms that never occur with athlete's foot (tinea pedis): toe injury
Irritant contact dermatitis
Irritant contact dermatitis means a skin reaction that is caused by directly touching an irritating substance, and not by an infectious agent such as a bacteria or virus.
Common causes are soap, bleach, cleaning agents, chemicals, and even water. Almost any substance can cause it with prolonged exposure. Contact dermatitis is not contagious.
Anyone who works with an irritating substance can contract the condition. Mechanics, beauticians, housekeepers, restaurant workers, and health care providers are all susceptible.
Symptoms include skin that feels swollen, stiff, and dry, and becomes cracked and blistered with painful open sores.
A medical provider can give the best advice on how to heal the skin and avoid further irritation. Self-treatment can make the problem worse if the wrong creams or ointments are used.
Diagnosis is made through patient history, to find out what substances the patient comes into contact with, and through physical examination of the damaged skin.
Treatment involves avoiding the irritating substance if possible. Otherwise, the person can use petroleum jelly on the hands underneath cotton and then rubber gloves.
Top Symptoms: rash with well-defined border, itchy rash, red or pink, rough patch of skin, painful rash, red rash
Symptoms that always occur with irritant contact dermatitis: rash with well-defined border
Symptoms that never occur with irritant contact dermatitis: fever, black-colored skin changes, brown-colored skin changes, blue-colored skin changes
Allergic contact dermatitis of the foot
Allergic contact dermatitis is a condition in which the skin becomes irritated and inflamed following physical contact with an allergen. Common products known to cause allergic dermatitis include plants, metals, soap, fragrance, and cosmetics.
Top Symptoms: foot redness, foot/toe itch, scabbed area of the foot
Symptoms that always occur with allergic contact dermatitis of the foot: foot redness

Cracks in or between the toes treatments and relief
The mainstay of treatment in regards to cracks between the toes is prevention. There are many things you can do at home or in your day-to-day routine that can stop this condition from occurring in the first place.
Since many of the causes of cracks in or between the toes can persist or thrive in a moist environment, keeping your feet dry is key. Try these lifestyle changes in order to prevent the occurrence or recurrence of your symptoms:
- Keep your feet dry: Thoroughly dry your feet with a towel after activities such as showering or swimming.
- Footwear: Wear shoes that fit and are not too tight. This will allow your feet to breathe. Try not to wear the same pairs of shoes over consecutive days and take your shoes off as much as possible. You should also wear flip-flops in communal showers and changing rooms.
- Limit the spread of germs: Do not share towels, shoes, or socks.
There are many creams, gels, and sprays that are available over-the-counter that do not require a prescription. Always speak with your physician first before trying any non-prescription treatments.
When to see a doctor
If you develop symptoms, see your healthcare provider for an appropriate diagnosis and advice on how to treat your condition. For example, if your symptoms are due to a fungal infection, your healthcare provider may give you over-the-counter options to utilize. However, if your symptoms are dermatologic or systemic in nature, your healthcare provider may have to prescribe topical or systemic steroids to treat your condition.
When it is an emergency
Cracks in or between the toes are rarely an emergency. However, if you have a weakened immune system or peripheral nerve problem from a condition such as diabetes, you need to pay particularly close attention to your feet. In such conditions, cracks in the feet may go unnoticed for long periods of time and become super infected.
