Drag socks are swimming resistance training tools designed to enhance strength, endurance, and leg power. These socks are essentially closed-bottomed mesh polyester bags worn on the feet, providing swimmers with additional resistance to improve leg performance, regardless of their swimming style.
These socks can be utilized by both novice swimmers to refine their swimming technique and professionals to intensify their training. In some cases, drag socks are employed as an alternative to fins since they can offer a similar resistance effect without the need for bulky equipment.
