Article in English: Cotton socks are generally a good choice. Make sure that the socks are neither too tight nor too loose!  Wear high socks or low socks, to your taste. Short socks will give your legs more space to breathe, but high socks can be useful for wicking away sweat. Tight socks can constrict your legs and slow your blood circulation. On the other hand, socks that are too loose might distract you by sliding down your legs. As you move about the gym, use a soft, clean towel to wipe your sweat away. You don't want to leave your sweat on the seat of a machine! Most gyms provide clean towels for members to use during their workouts. Do not share a towel with anyone, or else you risk sharing germs! Clean up any sweat that you do leave on a machine. Use a small, clean towel to wipe down the seat, the bars, and any other part that your sweat has touched. Your sweat carries bacteria that could infect someone else if left to dry on the machine! Even your own sweat, when left to dry on fabric, can breed nasty bacteria and then infect you. Odor-making bacteria tend to grow better on polyester than on cotton – but you should wash all gym clothes regardless.
