Researchers believe that hyperhidrosis, or excessive foot sweating, is an inherited condition, according to the American Podiatric Medical Association. Medical science does not completely understand why hyperhidrosis occurs, but people affected by the condition sweat most of the time, whereas other people only sweat when they get warm.
Hyperhidrosis sometimes causes feet to sweat so profusely that they slide around inside the affected personﾒs shoes, notes APMA. Feet can take on a wet, whitish appearance, and foot infections are prevalent in people with the condition, since continual wetness causes a breakdown of the skin and allows infections to flourish. Most people with the condition also experience foot odor due to the constant perspiration of their feet.
Anxiety and emotional stress are also common among hyperhidrosis sufferers, notes the APMA. People affected may worry that others smell their feet, and they may become isolated as a result.
Battling hyperhidrosis requires strict attention to foot hygiene, reports APMA. A good hygiene routine includes washing the feet thoroughly, including between the toes, and drying the feet before applying foot powder, antifungal powder or corn starch to the feet. Wearing socks that wick moisture away from the feet can also help, and APMA recommends changing socks throughout the day and wearing shoes crafted from breathable materials to help combat the problem.
