Causes of stinky feet

Feet have thousands of sweat glands and when this moisture gets trapped in socks or shoes it can cause a bad odor. However, there is more to stinky feet than sweat alone.

A multitude of bacteria on the bottom of the feet feed on the sweat which causes them to produce an acid that smells. Athlete's foot and other types of fungus can also thrive in the warm, moist environment inside shoes and socks and create an unpleasant odor.

In addition, some factors can make people more susceptible to sweaty feet and odor. These include medical conditions like hormonal changes during puberty or excessive sweating due to hyperhidrosis.

Finally, bad habits like poor hygiene, not wearing fresh socks daily, and not rotating shoes often enough can cause an issue.

Treatment options

There are several steps people can take to reduce foot odor. They include:

Practice good hygiene

Wash feet at least once a day and be sure to dry them thoroughly afterward. Address places where bacteria could grow such as between the toes and in dead skin on the foot by carefully drying between the toes after showering or bathing and removing dead skin with a foot file. Keep toenails short and clean.

Change footwear

Socks should be changed daily or more often when feet become particularly sweaty like after exercising or in a hot environment.

Rotate between two or more pairs of shoes to allow them to dry for a full day before wearing them again. If there are removable insoles take them out to allow for more thorough drying.

Consider the type of socks and shoes

Socks should absorb moisture and be made from natural fibers. Shoes should be roomy rather than too small or tight. In addition, wear sandals when possible and go barefoot indoors to help keep the feet dry.

Try specific treatments

A small amount of rubbing alcohol on the bottom of the feet nightly can help encourage more dryness. An antiperspirant or deodorant spray on the feet can also aid in reducing odor.

Antifungal and antibacterial soaps as well as antifungal foot spray or medicated foot powder may also decrease problems with smelly feet.

Seek professional help

If these home remedies don't provide relief or if the amount of sweating or odor is significant, a doctor can help. Possible solutions may include prescription antiperspirants and foot soaps as well as medical treatment for excessive sweating if warranted.
