Quick Answer
Pitted keratolysis is a bacterial skin infection causing small crater-like pits on the soles of the feet, usually accompanied by a strong odor. It is caused by Kytococcus sedentarius or Corynebacterium bacteria thriving in moist, warm conditions. Treatment involves topical antibiotics (erythromycin 2% or clindamycin gel) applied twice daily for 2–4 weeks, combined with moisture-control strategies like antiperspirant foot sprays and breathable footwear.

How to Get Rid of Pitted Keratolysis Once & For All
Pitted keratolysis is one of those conditions that people often suffer with for months or years — partly because it looks like athlete’s foot or a wart, and partly because it’s treated with the wrong things. If you’ve noticed shallow pits or craters on the soles of your feet along with a distinctive unpleasant smell, here’s exactly what pitted keratolysis is and how to eliminate it for good.
What Is Pitted Keratolysis?
Pitted keratolysis is a bacterial skin infection caused by Corynebacterium species (sometimes also Kytococcus sedentarius or Dermatophilus congolensis). The bacteria produce enzymes that digest the top layer of skin, creating characteristic small craters or pits. Unlike athlete’s foot — which is fungal — pitted keratolysis is bacterial and requires a completely different treatment approach.
It’s one of the most underdiagnosed foot conditions — many patients (and even some healthcare providers) mistake it for a fungal infection or excessive callus buildup.
Recognizing Pitted Keratolysis: The Key Signs
- Small pits or craters in the skin of the sole — typically 1–7mm in diameter, often clustered
- White or yellowish discoloration of the affected areas
- Strong, characteristic odor — described as sour, cheesy, or sulfurous. This is the most distinguishing symptom.
- Worse when feet are wet — the pits become more visible after bathing or sweating
- Most common on weight-bearing areas — ball of foot, heel, toe tips
- Usually painless, but may cause mild tenderness or itching
What Causes It?
The bacteria that cause pitted keratolysis thrive in warm, moist, enclosed environments. Contributing factors include:
- Excessive foot sweating (hyperhidrosis) — the primary driver
- Wearing closed shoes or boots for extended periods
- Synthetic socks that trap moisture
- Working in hot, humid environments
- Prolonged standing or physical labor
- Poor ventilation of footwear
Athletes, military personnel, healthcare workers, and manual laborers are at highest risk.
How to Treat Pitted Keratolysis
Step 1: Address the Moisture Problem (Critical)
Without controlling sweat and moisture, antibiotic treatment will keep failing. This is the most important step:
- Switch to moisture-wicking or wool socks — never 100% cotton, which holds moisture
- Use antiperspirant on your soles — yes, the same type you use under your arms. Apply prescription-strength aluminum chloride (Drysol) or 20% aluminum chloride to the soles at bedtime for 2–4 weeks
- Alternate shoes daily — give each pair 24 hours to dry out completely
- Use breathable footwear — leather or mesh rather than synthetic materials
- Use foot powder (zinc oxide or talc-based) to absorb excess moisture throughout the day
Step 2: Topical Antibiotic Treatment
Prescription topical antibiotics are the mainstay treatment. Your podiatrist or doctor can prescribe:
- Erythromycin 2% gel or solution — apply twice daily to affected areas for 3–4 weeks
- Clindamycin 1% gel or lotion — equally effective, also applied twice daily
- Mupirocin (Bactroban) — another effective option
- Benzoyl peroxide (5–10%) wash — available OTC as a face wash but highly effective for pitted keratolysis when used as a foot soak or applied directly
Step 3: Daily Hygiene Protocol
- Wash feet with antibacterial soap or benzoyl peroxide wash daily
- Dry thoroughly between all toes — pat, don’t rub
- Change socks daily (or more frequently if sweating heavily)
- Disinfect footwear with antibacterial spray or UV shoe sanitizer
Why “Once & For All” Requires Maintenance
Pitted keratolysis responds well to treatment — most patients see significant improvement within 2–3 weeks of starting topical antibiotics plus moisture control. However, the bacterial environment is re-established quickly if you return to the same sweaty footwear habits that caused it.
Long-term prevention requires:
- Continued use of moisture-wicking socks
- Regular antiperspirant application during high-sweat periods
- Rotating and properly airing out footwear
- Annual check-in with your podiatrist if prone to recurrence
⚠️ When to See a Podiatrist for Pitted Keratolysis
Many people treat this themselves with antifungal cream for months — and wonder why it isn’t working. See a podiatrist if:
- You’ve been treating what you think is athlete’s foot for more than 6 weeks without improvement
- There is a strong or unusual odor from your feet
- You notice pits or craters in the skin (not just scaling)
- The condition keeps recurring despite treatment
- You have diabetes — any foot skin infection needs prompt professional attention
