Why do feet perspire?
There are about 250,000 sweat glands on the skin of your feet – more than any other part of your body. Sweat is perfectly natural, keeping the skin soft and flexible and controlling the temperature of your feet. People often think that sweat is the cause of bad odours, but it isn’t. Odour is produced by bacteria which grow in shoes due to the heat and humidity. They attack the sweat molecules, decomposing them and generating the bad smell.
How to manage bad foot odours
To take care of excessive perspiration, wear socks made of natural materials like cotton, and shoes that allow your feet to breathe to help reduce the growth of bacteria that cause bad odour. If you have stubborn perspiration, an antiperspirant spray can help, but shoe hygiene is essential too. Try using a spray deodorant for shoes or insoles made from activated charcoal to help eliminate bad odours.
