Why do you get sores in the underside creases of your toes?

Sores in the underside creases of your toes, also known as toe blisters or friction blisters, are commonly caused by excessive friction or pressure on the skin. This can occur due to various factors, including:

1. Ill-Fitting Shoes: Wearing shoes that are too tight, too loose, or have an improper fit can cause the toes to rub against the material, leading to blisters.

2. Long-Distance Walking or Running: Prolonged physical activities, especially without proper cushioning or support, can cause friction between the toes and the shoe, resulting in blister formation.

3. Sweaty Feet: Moisture from sweaty feet can soften the skin and make it more susceptible to friction, increasing the risk of blisters.

4. Incorrect Socks: Wearing socks that are too thin or too thick, or made from materials that don't wick away moisture, can contribute to blister development.

5. Foot Deformities: Some foot deformities, such as hammertoes or bunions, can cause the toes to rub against each other or against the shoe, leading to blisters.

6. Medical Conditions: Certain medical conditions, such as diabetes or peripheral neuropathy, can cause reduced sensation in the feet, making individuals less likely to notice blisters until they become severe.

7. New Footwear: Wearing a new pair of shoes that haven't been broken in can increase the risk of blisters as the material stretches and molds to your foot.

8. Toe Trauma: Direct injuries or impacts to the toes can cause blisters to form.

9. Infections: Blisters can also be caused by infections, such as athlete's foot or bacterial infections.

If you experience toe blisters, it's important to take steps to prevent further irritation and promote healing. This includes wearing shoes that fit properly, using blister prevention products, keeping your feet dry, and applying appropriate treatments or consult with a healthcare professional if they are severe or persistent.
