1. The Material: Humidity's Enemy
This is the most important criterion. Forget 100% cotton. A high-performance tennis sock is made from synthetic materials (polyester, polyamide, elastane) which have hydrophobic properties.
They do not retain moisture, but rather wick it away from the surface of your skin to the outside of the sock, where it can evaporate. Your feet thus remain drier, and your skin more resistant.
