Anyone can get sweaty feet, regardless of the temperature or time of year. But teenagers and pregnant women are especially prone because hormonal changes make them sweat more.
You’re also more likely to have foot perspiration if you’re on your feet all day, if you’re under a lot of stress or if you have a medical condition called hyperhidrosis, which makes you sweat more than usual. Fungal infections, such as athlete’s foot, can also lead to bad foot odour.
According to podiatrist, Lorraine Jones, feet become smelly if sweat soaks into shoes and they don’t dry before you wear them again.
Bacteria on the skin break down sweat as it comes from the pores. A cheesy odour is released as the sweat decomposes.
“Your feet sweat into your shoes all day so they get damp and bacteria start to grow. The bacteria continue to breed once you’ve taken your shoes off, especially if you put them in a dark cupboard. Then, when you put your shoes back on the next day, even if you’ve just had a shower, putting your feet into still damp shoes creates the perfect conditions for the bacteria to thrive – warm, dark and moist.”
