Wearing shoes without socks causes increased sweating, and shoes can become very damp and moist. Damp shoes become smelly, and bacteria grow like crazy. 5) Change your socks and shoes: Change your socks and shoes after work or after the gym. A clean, dry pair of socks can make a big difference for sweaty feet. 6) Avoid wearing plastic shoes: Flip-flops look disgusting after prolonged usage for a reason. The plastic causes feet to sweat. If you have sweaty feet and are choosing a sandal, choose a sandal with a leather upper. 7) Alternate shoes: Don’t wear the same shoes multiple days in a row; give the shoes a chance to dry out completely to prevent bacteria and fungus from growing.
