Check if you have dry, cracked skin. In many cases, the root of itchy feet is overly dry skin. Inspect your feet and see if your skin is flaky or cracked. Also rub them and see if they feel rough. These symptoms indicate overly dry skin, which is probably the cause of your itching.^{[1]XTrustworthy SourceCleveland ClinicEducational website from one of the world's leading hospitalsGo to source}
- If your skin is cracked enough that your feet bleed, see your doctor right away. This can lead to a serious infection for someone with diabetes.
2
Avoid scratching your feet. While it may be tempting, scratching your itchy feet can do more damage. If your skin is dry, it cracks more easily, so you can cut yourself if you scratch too hard. Even small cuts can get infected when you have diabetes.^{[2]XTrustworthy SourceAmerican Diabetes AssociationHealth-based nonprofit focused on preventing and researching diabetesGo to source}
- If you have been scratching and there are cuts on your feet, visit your doctor right away.

Wash your feet daily with lukewarm water. Keeping your feet clean helps avoid dry skin. When you wash your feet, use only lukewarm water. Hot water can irritate your skin and cause further itching. Always test the water with your hand before washing your feet. If you can’t keep your hand in the water because it’s too hot, either wait for the water to cool down or turn the hot water down.^{[3]XResearch source}
- As a general guideline, use water that is the same temperature you would use on a newborn baby.
- When washing, use a soft sponge or washcloth. Don’t rub your feet hard because this can cause further irritation.
4
Use hypoallergenic and fragrance-free soap when you wash your feet. Perfumes, fragrances, dyes, and harsh soaps can cause reactions on your skin. When you wash, use only hypoallergenic and fragrance-free soaps that are gentle on your skin.^{[4]XTrustworthy SourceCleveland ClinicEducational website from one of the world's leading hospitalsGo to source}
- Do not take bubble baths. These chemicals can dry out your skin further.
- If you need guidance on buying skincare products, ask your doctor for suggestions.
5
Blot your feet dry with a towel after washing them. Make sure they are completely dry by gently blotting them with a towel. Do not rub, because this can irritate your skin. Do not get dressed until your skin is dry because your clothes can trap moisture, especially in humid weather.^{[5]XTrustworthy SourceCleveland ClinicEducational website from one of the world's leading hospitalsGo to source}
- Remember to dry in between your toes. Moisture here can cause fungal infections.
6
Apply a gentle moisturizer to your feet daily. Moisturizers help prevent dry, itchy skin. Use a fragrance-free moisturizer after washing your feet to prevent your skin from drying out. Follow the application instructions on the product packaging.^{[6]XResearch source}
- Do not apply any cream between your toes. The extra moisture can encourage fungal growth.
7
Wear socks designed for people with diabetes. These socks are designed with extra cushioning and moisture-wicking material. They keep your feet dry and help prevent skin irritations.^{[7]XResearch source}
- If you don’t wear specialized socks, make sure you change into clean, dry socks every day.
8
Drink the daily recommended amount of water. Staying hydrated helps keep your skin moist and healthy. Prevent dryness and cracking by drinking water regularly throughout the day.^{[8]XTrustworthy SourceCleveland ClinicEducational website from one of the world's leading hospitalsGo to source}
- The daily recommended amount of water 15.5 cups (3.7 liters) for men and 11.5 cups (2.7 liters) for women. Use this as a guideline for your daily intake.^{[9]XTrustworthy SourceCleveland ClinicEducational website from one of the world's leading hospitalsGo to source}

1
Look for rashes or bumps indicating an infection. Diabetes leaves your feet susceptible to bacterial or fungal infections that may cause itching. Inspect your feet for any red patches. These may be raised or bumpy. Blistered skin is also a symptom of a fungal infection. If these signs are present on your feet, the itching may be from some kind of infection.^{[10]XTrustworthy SourceCleveland ClinicEducational website from one of the world's leading hospitalsGo to source}
- Remember to check between your toes. Some fungal infections like athlete’s foot primarily grow in between the toes.
Tip: A rash that's accompanied by swelling, dry skin, and possibly scaling may be caused by venous insufficiency, which means your veins in your legs aren't working well. Visit your doctor to make sure you're okay.
2
Contact your doctor if you think you have a fungal infection. Most fungal infections are harmless and only cause itching, but someone with diabetes is at risk for further infections. If you inspect your feet and find signs of a fungal infection like red skin or blisters, contact your doctor right away. They will advise you best on how to proceed.^{[11]XTrustworthy SourceAmerican Diabetes AssociationHealth-based nonprofit focused on preventing and researching diabetesGo to source}
- If you're having recurring fungal infections, it might be a sign of worsening uncontrolled blood sugar or undiagnosed diabetes. Getting your blood sugar under control can help prevent these infections.
3
Apply antifungal cream to your feet. If your doctor inspects your feet and diagnoses you with a fungal infection, the first step will probably be applying antifungal cream to the area. Your doctor may recommend an over the counter product or write you a prescription for a stronger medication.^{[12]XTrustworthy SourceCleveland ClinicEducational website from one of the world's leading hospitalsGo to source}
- Follow all the instructions that your doctor gives you on using the cream properly.
- Common application instructions include washing and drying your feet completely, then applying the cream to the affected area twice a day.
4
Keep the humidity low in your home. Fungal infections grow in damp environments. If you live in a humid area, your skin will stay wet if you sweat or bathe. Use a dehumidifier to keep your home’s humidity low. This can prevent fungal infections and stop existing ones from spreading.^{[13]XTrustworthy SourceCleveland ClinicEducational website from one of the world's leading hospitalsGo to source}
- If you don’t keep the humidity low in your home all the time, at least turn on the dehumidifier when you bathe, or only bathe when humidity is low. If humidity is high, your body will take a long time to dry. This could encourage fungal growth.
5
Use an antiperspirant on the bottom of your feet. If you have a problem with sweaty feet, you may be more susceptible to fungal infections. Prevent this problem by applying an antiperspirant to the soles of your feet. Make sure the product you use is fragrance-free and hypoallergenic.^{[14]XResearch source}
- Check with your doctor before doing this. An antiperspirant may interact with other products you use on your feet.
6
Wear clean socks every day. Fungal infections can remain in your socks and re-infect you when you put them back on. Avoid this possibility by wearing clean, dry socks every day. Always wash your socks thoroughly before wearing them again.^{[15]XResearch source}
- Specialized socks for people with diabetes may also help prevent fungal infections. These socks are designed with moisture-wicking material that keeps your feet dry.

1
Inspect your feet for symptoms of poor circulation. Sometimes itching is caused by poor blood circulation, a common problem for people with diabetes. If the itching is accompanied by any of the following symptoms, poor circulation is probably the cause.^{[16]XTrustworthy SourceCleveland ClinicEducational website from one of the world's leading hospitalsGo to source}
- A pale blue color in your feet or lower legs.
- Numbness or tingling.
- Your feet feeling cold to the touch.
- Your calves feel painful while you're active and feel better at rest.
Warning: In some cases, poor circulation might be a sign of peripheral artery disease. Diabetes is a risk factor for this condition, so it's important that you talk to your doctor about what you're experiencing so you can get treatment.
2
Get at least 30 minutes of physical activity 5 days per week. When poor circulation is the cause of your itching feet, you can take several actions to improve circulation. An important one in staying active. When you're sedentary, blood doesn't travel as well. Fix this by getting the recommended 30 minutes per day of physical activity. This can bring more blood to your feet and help the itching.^{[17]XTrustworthy SourceNational Institute of Diabetes and Digestive and Kidney DiseasesHealth information from the National Institute of Diabetes and Digestive and Kidney Diseases, a division of the U.S. National Institutes of HealthGo to source}
- You can break this exercise up into several sets throughout the day. For example, you could take a 10-minute walk in the morning and go for a 20 minute run in the evening.^{[18]XTrustworthy SourceCleveland ClinicEducational website from one of the world's leading hospitalsGo to source}
- You don't have to work out hard to meet this goal. Walking for a few minutes a day is a perfect exercise.
- If you haven't exercised in a while, start off small. Go for a 5-minute walk each day for a week. Then increase the time by 5 minutes every week.

Keep your blood sugar levels within the normal range. An abnormal blood sugar level can cause poor circulation. Do your best to manage your diabetes symptoms and maintain a normal blood sugar range. A normal range is usually between 70-100 mg/dl (4 and 9 mmol/L) or an A1C less than 5.7%, depending on the type of diabetes you have.^{[19]XTrustworthy SourceCenters for Disease Control and PreventionMain public health institute for the US, run by the Dept. of Health and Human ServicesGo to source}
- Diabetes patients can maintain a normal blood sugar range by taking their medication and eating 3 balanced meals a day. You should also avoid sugary food and drinks like soda.
- Also limit your alcohol intake. Speak with your doctor about drinking alcohol, because this can affect your blood sugar as well.
4
Maintain a healthy cholesterol level. High cholesterol can also inhibit your body's circulation. Consult with your doctor to find the right cholesterol level for you. If your cholesterol is high, take steps to meet and maintain this level to improve your circulation.^{[20]XTrustworthy SourceNational Institute of Diabetes and Digestive and Kidney DiseasesHealth information from the National Institute of Diabetes and Digestive and Kidney Diseases, a division of the U.S. National Institutes of HealthGo to source}
