Feet are home to a diverse range of bacteria and fungi, thriving in warm, moist conditions and feeding on sweat and dead skin, which causes foot odour.
Socks trap sweat, creating an ideal environment for these microbes, which can survive on fabrics for months, leading to high bacterial counts compared to other clothing.
Socks can harbour potential pathogens like Aspergillus, Candida, and Cryptococcus, and microbes can transfer to surfaces, potentially spreading infections such as Athlete's foot.
To reduce foot odour and bacterial growth, it is advised to change socks daily, wash feet twice daily, and consider antimicrobial or bamboo socks.
For effective sock hygiene, wash at 60°C with enzyme detergent, or use a hot iron or outdoor drying if low-temperature washing is unavoidable, to kill residual bacteria and fungi.
