Few things are more frustrating than a nagging, deep itch on the bottom of your foot. Maybe the itchy, tingling sensation kicks up while you’re walking for long periods of time, while wearing tight socks, or as you’re drifting off to sleep at night. Usually, the cause of prickly feet is easy to pin down (and treat), but sometimes, it may be a sign of an underlying health condition.

Here, we spoke with Lauren Ploch, MD, MEd, a board-certified dermatologist in Georgia, to learn what causes that deep itch on the bottoms of your feet, and how to get relief—with natural remedies and doctor-approved meds.
10 causes of a deep itch on the bottom of your feet
1. Dry skin
Sometimes itchy feet are just from dry skin. It is one of the most common places to get dry skin, after all, per the Cleveland Clinic. When your skin lacks moisture, it can become scratchy. Other telltale signs include the following, per the Cleveland Clinic:
- Rough patches of skin
- Skin that’s scaly or flakes easily
- Skin that cracks and/or bleeds
- Skin that’s lighter or darker than your normal skin tone, or red to purple
- Tight skin
How to treat it:
Moisturize, moisturize, moisturize. It will safeguard your skin’s barrier, keeping it soft and supple. Look for products with emollients (which soothe and hydrate the skin) and hyaluronic acid (which increases moisture in the skin), according to the Cleveland Clinic.
2. Athlete’s foot
Your itchy feet could be caused by fungi (unfortunate, but true). Athlete’s foot—also called tinea pedis—is a fungal infection that triggers an itchy, scaly rash. You can catch it by touching someone who has it, or by touching their belongings—like their socks, towels, or shoes. The fungus can also spread from your feet to other parts of your body.
Other symptoms of athlete’s foot may include the following, according to the Mayo Clinic:
- Scaly, peeling, or cracked skin between the toes
- Inflamed skin that might appear reddish, purplish, or grayish, depending on your skin color
- Burning or stinging
- Blisters
- Dry, scaly skin on the bottom of the foot that extends up the side
How to treat it:
Because athlete’s foot is contagious, you’ll want to nip it in the bud fast. Your dermatologist can treat it with an antifungal medication, says Dr. Ploch. There are some effective over-the-counter products for treatment available, notes the Cleveland Clinic. Just be sure to follow all the instructions carefully.
To avoid athlete’s foot in the future, keep your feet dry and cool. Fungi flourish in warm, humid conditions (like damp socks and tight-fitting shoes). Here are few tried-and-true tips to prevent tinea pedis, per the Mayo Clinic:
- Let your feet air out: Wear sandals when you can, and opt for breathable shoes.
- Wash your feet daily: Use warm, soapy water and rinse and dry your feet thoroughly, especially between the toes. Don’t forget to pat your feet dry after you bathe.
- Apply a medicated foot powder: if you’re prone to athlete’s foot.
- Change your socks at least once a day: And switch out of sweaty socks ASAP.
- Select moisture-wicking socks: If you’re prone to sweaty feet, fabrics like cotton wick moisture to help keep them dry.
- Use different shoes from day to day: This gives your shoes time to dry after each use. You can also invest in a couple pairs of breathable, lightweight running shoes to rotate.
- Protect your feet in public places: Wear waterproof sandals or shoes around public pools, showers, and locker rooms.
3. Other skin infections
Other types of skin infections can lead to itchy feet, too. One of the most common? A bacterial skin infection called impetigo—which causes itchy sores and blisters. It typically happens when bacteria enter broken skin (like a cut, bite, or scratch), though you can become infected even if your skin isn’t broken or punctured, according to the Cleveland Clinic.
Along with itchiness, other signs of impetigo may involve the following, per the Cleveland Clinic:
- Pus-filled blisters that burst easily
- A rash that causes red, raw skin
- Skin lesions
- Raw, shiny areas of skin that scab over with a yellowish-brown crust
- Swollen lymph nodes
Impetigo usually affects children (and forms around the mouth area) but adults can get it, too (and on any body part, including the feet), per the Cleveland Clinic. And like athlete’s foot, impetigo is highly contagious. You can catch it through contact with an infected person or contaminated surfaces.
How to treat it:
To stop the spread of impetigo, go to your doctor ASAP. They’ll prescribe a topical antibiotic (or an oral one, depending on the severity of the rash). You should see an improvement in your symptoms within a couple days of taking the medication.
4. Intrahepatic cholestasis of pregnancy
Itchy feet? If you’re pregnant, you can chalk it up to another strange symptom. Several things can cause itching during pregnancy—one being intrahepatic cholestasis of pregnancy, Dr. Ploch says. It’s a liver condition that triggers intense itching (usually in the hands and feet) without a rash. It typically happens in the third trimester, and the itch gets stronger at night, according to the Mayo Clinic. (We know, as if your growing belly, back pain, pregnancy indigestion weren’t causing enough sleepless nights.)
Like most other pregnancy symptoms, hormones are to blame. “During pregnancy, hormones can slow down the biliary system,” i.e., the organs that make and store bile, Dr. Ploch says. When this happens, bile-related byproducts build up and enter the bloodstream, she says. And this leads to the intense itching.
Other less common symptoms of intrahepatic cholestasis of pregnancy include the following, per the Mayo Clinic:
- Yellowing of the skin and whites of the eyes, called jaundice
- Nausea
- Loss of appetite
- Oily, foul-smelling stools
How to treat it:
If you get extreme itchiness during pregnancy, tell your OB/GYN or midwife immediately. Intrahepatic cholestasis of pregnancy can cause potentially dangerous complications for you and your baby, so your provider will want to monitor you both carefully.
5. Contact dermatitis
If your feet are dry, itchy, and red, you could be dealing with contact dermatitis. This condition—which can occur anywhere on your body—happens when you come into contact with something (like an irritant or allergen) that triggers a skin reaction.
When your skin encounters an irritant or allergen, your immune system kicks into gear. The itchiness you feel is one sign that your white blood cells—i.e., your body’s defenders—are at work. “For example, some [white] blood cells (called eosinophils) in our body can increase a particular neuropeptide in peripheral neurons and, therefore, trigger itch,” Dr. Ploch says.
According to the Cleveland Clinic, contact dermatitis can also cause a rash that may be:
- Red, purple, or darker than your natural skin tone
- Swollen, hive-like, or elevated from the skin surrounding it
- Bumpy with a small cluster of pimples or blisters
- Oozing fluid or pus
- Painful with a burning or stinging sensation
- Flaky or scaling
How to treat it:
The best way to reduce contact dermatitis is to avoid the thing that’s causing your skin reaction. The most common allergens that cause contact dermatitis include the following, per the Cleveland Clinic:
- Plants or parts of a plant (botanicals), like poison ivy
- Skin-care products with fragrances
- Metals, such as nickel
- Medications, including antibiotics
- Preservatives or chemicals
The most common irritants that cause contact dermatitis include the following, per the Cleveland Clinic:
- Acids
- Cleaning products
- Body fluids, including urine and saliva
- Plants, like poinsettias and peppers
- Hair dyes
- Nail polish remover or other solvents
- Paints and varnishes
- Soaps or detergents
- Resins, plastics, and epoxies
In the meantime, you can minimize your itchy, inflamed skin with over-the-counter (OTC) remedies like anti-itch creams, topical or oral antihistamines, and/or corticosteroid creams.
6. Other skin conditions
Itchy skin is a hallmark symptom of conditions like eczema and psoriasis, which can affect all different parts of your body—including the soles of your feet. Eczema weakens your skin’s barrier function and leads to itchy, dry, bumpy, or leathery patches of skin, according to the Cleveland Clinic.
Psoriasis, on the other hand, is an autoimmune condition that can cause thick, scaly areas of skin (called plaques), pain, cracked or pitted nails, and even joint pain, per the Cleveland Clinic.
How to treat it:
If you have a mild case of eczema or psoriasis, moisturizers can help manage the itch. “The safest treatment for itch is a bland OTC moisturizing cream that has ceramide lipids,” Dr. Ploch says.
For severe cases, topical steroid creams may also be prescribed. “But there are several non-steroidal medications that are safer and more appropriate based on the underlying condition,” Dr. Ploch says. Talk with your dermatologist about your options.
And keep in mind: Dr. Ploch cautions against treating “itch with OTC corticosteroid creams, because this can worsen some conditions.”
7. Bug bites
Is there anything itchier than a fresh mosquito bite? (We’ll answer that for you: no.) If you were recently outside without shoes (especially in the summertime), it’s possible a mosquito made a meal of your exposed feet.
When mosquitoes (and other insects) bite you, they secrete saliva into your skin. This foreign substance activates your immune system, which processes the saliva as an allergen and releases chemicals like histamine, according to Columbia University Irving Medical Center. Histamine is what causes the area to itch and swell.
How to treat it:
For most bug bites, itching will begin to fade within 48 hours. In the meantime, resist the urge to scratch (we know, it’s really hard). But scratching just releases more histamine, making the bite even itchier, per Columbia University Irving Medical Center. Plus, you can break the skin if you scratch too hard, which can lead to possible infection.
Instead, minimize the itch with these tips from Columbia University Irving Medical Center:
- Wash the site with soap and water. Or wipe with an antibacterial wipe or soap.
- Apply an ice pack to the site for 10 minutes. Repeat as needed.
- Take a (non-drowsy) antihistamine. Some examples include Zyrtec, Allegra, or Xyzal.
- Use an OTC anti-itch or antihistamine cream: This could include hydrocortisone, or even a homemade baking soda paste.
Most bug bites don’t require a trip to the doctor, but if your bite doesn’t seem to be getting better after a day or so, or it appears to worsen, you may have had an allergic reaction or infection. Seek immediate medical care if you get the following symptoms, per Columbia University Irving Medical Center:
- If you have reactions off-site (for instance, you were bitten on your foot, but your leg is swelling)
- You have hives everywhere
- You’re coughing, dizzy, nauseated, or vomiting
- You have diarrhea or trouble breathing
- You fainted immediately, or shortly after the bite or sting
8. Diabetes
At first glance, itchy feet and diabetes may not seem connected. But diabetes can affect many organs—your skin included.
People with diabetes can get localized itching (especially in the lower limbs and feet) due to poor circulation, according to the American Diabetes Association (ADA). Poor circulation happens when blood vessels become hard or narrow over time from high blood glucose levels. Diabetic polyneuropathy, a type of nerve damage, can also lead to feeling itchy, per an April 2021 review in the journal Advances in Dermatology and Allergology.
What’s more, folks with diabetes are also more prone to conditions that cause itch—like yeast infections (think: athlete’s foot) and dry skin, per the ADA.
How to treat it:
First and foremost, if you notice any changes in your feet, see your doctor. Left unchecked, diabetes can cause potentially life-threatening complications. Along with keeping your condition under control, the key to preventing itchy feet with diabetes is proper foot care. Try these simple strategies, per the ADA:
