Here are some causes and treatment options for Plantar Hyperhidrosis (aka: Sweaty feet)
More common in men.
Causes: excess heat, exercise, stress. Changes during puberty, pregnancy and menopause can also increased foot sweating. People who stand all day for their job can find their feet sweat more.
Things you can do:
Dry your feet well after shower especially between toes to prevent fungal infections
Change socks at least once a day
Socks made from natural fabrics like cotton or bamboo fibers are the best option, as they draw moisture away from the feet.
Wear shoes made from breathable materials, like canvas or leather
Don’t wear the same pair of shoes every day
Deodorising insoles and foot powders can help to absorb sweat and keep shoes fresh.
