Dealing with Sweaty Feet.
If your feet are constantly sweaty, you may suffer from a condition called hyperhidrosis. To cope with excess sweating, the American Podiatric Medical Association suggests the following: wash your feet daily with antibacterial soap; dry your feet well and sprinkle cornstarch, foot powder, or antifungal powder on your feet; wear socks made of synthetic materials to help wick sweat from your feet; choose shoes made of breathable material; and keep and extra pair of socks with you and change them during the day.
