In Japan, where you take your shoes off indoors, smelly shoes are a worry that other people discover at the entrance hall (玄関, genkan). "Will deodorant spray solve it?" and "is it fine to wear the same shoes every day?" are asked abroad too. Knowing where the smell comes from changes the approach.
| Cause | Mechanism | Measures |
|---|---|---|
| Moisture | Feet produce about 200 mL of sweat a day. Inside a shoe it reaches about 90% humidity and 35°C | After a day's wear, dry for 1–2 days; take out the insoles; drying agents, newspaper, wooden shoe trees |
| Bacteria | Break down skin oil and dead skin, releasing isovaleric acid, acetic acid and others | Fresh socks every day; wash between the toes and around the nails; care for hard skin (see the heel article) |
| Material | Synthetic leather and rubber breathe poorly and dry slowly | Breathable materials; rotation |
| Socks | Synthetics dry fast but hold odour; cotton absorbs but dries slowly | A moisture-wicking, quick-dry blend; five-toe socks (5本指ソックス); carry a spare pair |
| Washable shoes | Trainers etc. | Wash monthly and dry completely (see the trainers article) |
[Verify] Sweat volume and in-shoe temperature and humidity are general figures. Check the odour compounds against Japanese Dermatological Association and textile-industry material.
It only holds the smell down for a while. Dry, wash, change socks comes first.
The inside of a shoe does not dry overnight. Rotating 2–3 pairs is the single most effective measure.
Direct sun hardens leather and degrades synthetic leather. Shade with good airflow, insoles out. UV only kills what is on the surface.
Bacteria stay between the toes, around the nails and in the hard skin on the heels. Wash between the toes, dry completely, then put on socks. Keep nails short.
It is a moisture-and-bacteria problem, and shoes, socks and how you wash change it a great deal. If it doesn't improve, or the skin peels or itches, see a dermatologist.
