Fungi are everywhere, and can easily sneak beneath your toenails and cause an unpleasant infection.
The American Podiatric Medical Association suggests these preventive steps:
Treat feet to regular, careful washing with soap and water and a thorough drying.
In public places, wear flip flops or shower shoes.
Swap hosiery, socks and shoes more than once per day.
Keep toenails trimmed and cut in a straight line. Disinfect nail clippers and other tools used on nails.
Avoid tight hosiery, and stick to well-fitting shoes made of materials that breathe.
Opt for socks made of synthetic materials that keep away moisture from skin.
Don't attempt to cover up fungus discoloration with nail polish.
