• Wear clean socks made of natural, breathable materials like cotton or wool; they absorb moisture.
• Put your shoes on a rotation to give them adequate time to air out. Wearing the same sneakers daily will trap moisture and odor, causing your foot stink to worsen.
• Instead of shoes, wear sandals outside during warm-weather months, and don’t wear shoes in your house. If you’re too delicate a flower to go without foot coverings in your house in the winter — geez, do you live on Hoth? — suck it up and limit yourself to warm socks.
