Causes and Risk Factors of Pitsoles
The main causes of pitted soles are moisture, heat, and poor ventilation of the feet. This creates an ideal environment for bacteria such as Micrococcus sedentarius and Coryne bacteria to grow and produce enzymes that damage the skin. Risk factors include:
- Sweaty Feet
- Damp socks and poorly ventilated shoes
- Poor hygiene
- Prolonged standing or walking, especially in warm conditions

Are pitted soles contagious?
No, welt soles are not contagious. You cannot transmit it to others, since the bacteria are normally already present on the skin. The condition is caused by a combination of bacteria and external factors such as moisture and heat.
Treating pitted soles
Treating pitted soles focuses on addressing the causes and eliminating bacteria. Here are some effective options:

PediSpray® – Foot spray against sweaty feet (aluminum chloride solution)
Excessive sweating is one of the main causes of pitted soles. Pedispray Foot Spray helps reduce sweating and neutralizes unpleasant odors. Using Pedispray daily will keep your feet dry and fresh.
- Before bedtime wash and dry feet thoroughly
- Apply PediSpray® and let it soak in well
- Next morning wash feet again
- Repeat for 2 to 5 days at a time
- As the skin becomes drier, a treatment of a few times a week (no longer daily) is sufficient
It may be that some time after treatment the sweaty feet problem reappears. A short follow-up treatment will then be necessary.
Always maintain good hygiene rules.
Use PediFris® Shoe Powder
Pedifris Shoe Powder is specially designed to fight the bacteria that cause pitted soles. This powder disinfects your shoes, killing the bacteria responsible for pitting and odor.
Home remedies: what to do for Potholes according to ‘Grandma Knows Council’
- Vinegar bath: Mix vinegar with water and soak your feet to kill bacteria.
- Baking soda: Apply a paste of baking soda and water to the affected areas. This absorbs moisture and kills bacteria.
While these methods can help, the use of medical products such as PediSpray® and PediFris® is often more effective for a long-term solution.
Although pitted soles are often treatable with the right products and hygiene, it is important to see a doctor if:
- Symptoms persist or worsen despite treatment.
- You notice the infection spreading or painful inflammation.
- No improvement is visible after several weeks.
The family doctor may then prescribe additional treatments, such as antibiotics, to control the bacterial infection.
Preventing Potholes
Good hygiene and shoes that minimize moisture and heat are essential to prevent pitted soles:
- Ventilate your shoes: Wear breathable materials such as leather.
- Alternate shoes: Allow shoes to dry for at least 24 hours.
- Clean socks: Put on dry, clean footwear daily, preferably cotton or wool.
- Hygiene: Wash your feet daily with mild soap and dry them well, especially between the toes.
