Foot Odour and Wetness

What causes foot odour and wetness?

Sweaty feet and smelly feet can be an embarrassing problem, but if you suffer from them you’re not alone. They are common problems affecting adults and children who wear shoes on a daily basis. It’s not unexpected that you may occasionally suffer from sweaty feet. Your feet have over 250,000 sweat glands, and the fungi or bacteria associated with all that sweat is the source of stinky feet. These bacteria and fungi can also spread and thrive inside your shoes, leading to smelly shoes.

People with sweaty feet usually have a genetic predisposition to sweating (also called hyperhidrosis), or are nervous, anxious, or under stress. As a result, your brain tells your body to produce more sweat to keep itself cool. This means you may experience smelly feet year-round and not just in the hot summer months.

The moisture associated with sweaty feet can lead to other foot issues, like nail problems, and warts.
