Overview
- An expert cites research showing 8–9 million bacteria per sock sample after a single wear, compared with about 83,000 on t‑shirts.
- Feet host up to roughly 1,000 bacterial and fungal species that thrive in warm, sweaty spaces between toes, driving distinctive odours.
- Microbes from unwashed socks can transfer to shoes, beds, couches and floors, and can spread athlete’s foot in communal settings.
- Effective cleaning steps include washing at 60°C with an enzyme detergent, using hot steam ironing if only low‑temperature cycles are possible, and drying in sunlight.
- Product choices that may reduce odour include antimicrobial socks containing silver or zinc and breathable bamboo socks that improve airflow.
