Why do boys feet smell bad?

The sweat glands in boys' feet are more active than those in girls' feet, and they produce a higher concentration of acids and bacteria. These acids and bacteria break down the keratin, a protein that makes up the skin, and produce a foul odor.

Boys also tend to wear shoes that are too tight or too closed, which can trap sweat and bacteria and make the feet smell even worse. In addition, boys are often more active than girls, and their feet sweat more as a result.
