Pitted soles | Treatment and prevention

What are welted soles?

Pitted soles, also known as “pitted keratolysis,” can occur with impaired hydration of the feet. We often see these problems when there are sweaty feet, a situation exacerbated by the constant wearing of work boots or safety shoes.

Bacteria can then spread undisturbed and attack the stratum corneum. This causes the characteristic skin abnormalities (pitting) and the typical, unpleasant odor.


How do pitted soles occur

The condition is caused by the bacterium “corynebacterium.

This bacterium multiplies rapidly in warm, moist environments, such as socks or shoes due to excessive sweating, and produces a substance that attacks the horny layer of the skin. This causes the skin to inflame and create pitting, also called pitted keratolysis.

Symptoms of pitted soles

Although pitting is the most prominent symptom, there are other features that fit this condition.
The most common characteristics are:

  • Pits in the skin or callus layer
  • White sole of foot
  • Foul odor (due to sweaty feet)
  • Itchy soles of feet
  • Irritation or pain
  • Loose skin on the sole of the foot

Are pitted soles contagious?

No, the condition is not contagious like foot fungus. The ailment results from a combination of conditions (heat and moisture). The causative bacteria normally live on everyone’s skin. So everyone is susceptible to this.

Treating pitted soles

Treatment of pitted soles (pitted keratolysis) often starts with addressing the underlying cause, which in many cases involves sweaty feet.

Combats the cause of pitted soles

To prevent excessive perspiration, you can use an aluminum solution such as PediSpray®. This remedy helps reduce sweat production on the treated skin.

  • 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.

For choice help, consult the following article with info on the best socks to keep your feet dry and comfortable.


Daily shoe change


Change shoes regularly and let them dry so that bacteria do not have a chance to multiply. Damp socks and shoes are the perfect breeding ground for bacteria.

Choose shoes that ventilate well and are made of natural material such as leather or canvas. These absorb moisture and improve air circulation.
If possible, walk barefoot as much as possible



Remove calluses


Calluses on the feet can contribute to bacterial growth because they absorb sweat. You can remove excess calluses using a file or rasp. This reduces moisture absorption and will reduce the likelihood of pitted soles.

However, it can be difficult to treat calluses in hard-to-reach areas. In such cases, it is wise to seek the expertise of a pedicurist or medical pedicurist.
