Collection: Foot Odor & Sweat

WHAT IS FOOT ODOR & SWEAT?

Foot odor is a type of body odor that affects the feet of humans. It is sometimes considered to be an unpleasant smell, but can also be the target of foot fetishism, more specifically as a form of olfactophilia.

It is one of the most widespread forms of olfactophilia: In a 1994 study, 45% of those with a foot fetish were found to be aroused by smelly socks and/or feet, but most importantly by the intensity of the smell produced by such bacteria

Smelly feet and/or shoes especially when you first take your shoes off are the most common signs of foot odor.

People who wear poorly ventilated shoes, synthetic or non-leather boots, or non-wicking socks made of polyester or nylon may be more likely to have persistent foot odor.

WHAT CAUSES FOOT ODOR?

The main cause is foot sweat (also see focal hyperhidrosis). Sweat itself is odorless; however, it creates a beneficial environment for certain bacteria to grow, producing odorous substances. These bacteria are naturally present on our skin as part of the human flora. The front part of the foot produces the most sweat.

The smell is exacerbated by factors that increase sweating, such as wearing closed-toe shoes. Sports footwear such as sneakers is often heavily padded inside which provides a perfect environment to trap moisture and allow the bacteria to thrive. Socks can trap foot hair, especially on the toes, and may contribute to odor intensity by increasing the surface area on which bacteria can thrive.

Given that socks directly contact the feet, their composition can affect foot odor. Synthetic materials like polyester and nylon afford less ventilation to the foot than do cotton or wool, leading to increased perspiration and odor, although they can also reduce the incidence of blisters by wicking away perspiration. Many synthetic socks are treated with chemicals to help reduce odor.
