Some types of socks and hose trap moisture, which encourages fungal growth.

Cotton's wonderful absorbent quality suddenly becomes a disadvantage, and your feet may feel sweaty and damp, especially after exercising. Synthetic materials that are designed to "wick" away moisture, allowing it to evacuate up the leg, are often the best choice. Most socks today are a blend of 80% cotton with 20% synthetic fiber (such as polyester or acrylic), although some are entirely synthetic, the better choice. Wool socks can keep your feet warmer, but may cause them to perspire excessively, which encourages fungal growth.
