Why is it that when my feet sweat socks get like a greenish yellowish color on your soles and smell ammonia?

Bromhidrosis, or smelly feet, is caused by bacteria that live on the skin of your feet. When these bacteria break down sweat, they produce acids that give off an unpleasant odor. The greenish yellowish color on the soles of your socks is likely caused by a type of bacteria called *Pseudomonas aeruginosa*. This bacterium is commonly found in soil and water, and it can also live on human skin. When *Pseudomonas aeruginosa* breaks down sweat, it produces a pigment called pyocyanin, which gives off a green color.

The ammonia smell is likely caused by another type of bacteria called *Staphylococcus hominis*. This bacterium is also commonly found on human skin, and it can produce ammonia as a waste product.

Preventing Smelly Feet:

There are a number of things you can do to prevent smelly feet, including:

* Washing your feet regularly with soap and water. This will help to remove bacteria from your skin.

* Drying your feet thoroughly after washing them. This will help to prevent bacteria from growing.

* Wearing socks that absorb moisture. This will help to keep your feet dry and prevent bacteria from growing.

* Changing your socks frequently. This will help to prevent bacteria from building up on your socks.

* Using an antibacterial soap or powder on your feet. This can help to kill bacteria that cause smelly feet.

* Avoiding wearing shoes that are too tight. Tight shoes can trap moisture and create a warm, moist environment that is ideal for bacteria growth.

* Consulting a doctor if you have a persistent foot odor problem. There may be an underlying medical condition that is causing the odor.
