Mix this with suffocating socks and tight shoes. Bacteria LOVES this type of environment and actually thrives in it. Dark, damp, and moist environments will cause and encourage bacteria.
Prevention includes always wearing clean socks, even changing them throughout the day if you seat excessively. Alternate your shoes, allow them time to dry out before you wear them again. Apply an antiperspirant to your feet daily such as Mycomist, a specially designed foot deodorant, which we offer in our office.
