The Science Behind Why Soccer Players the 26 World Cup Are Cutting Their Socks

> Professional soccer socks are, by design, form-fitting. In addition to holding shin guards in place, they provide support to the ankle, the arch of the foot, and the calf; they help manage moisture and reduce foot movement inside the cleat to improve stability. This design principle has been used in professional soccer for decades. Although materials have evolved to become lighter and more durable, they are still primarily based on synthetic fibers such as polyester, nylon, and spandex.

> There is a biomechanical component to this sensation. During a sprint or a change of direction, the largest muscle in the calf contracts and increases in thickness to generate the force that propels the athlete forward. This change in shape occurs thousands of times during a game. For some, the repeated expansion of the muscle is enough to create a sensation of pressure when the sock exerts constant compression on the calf.

Players complain about discomfort (the socks are too tight) and the players cut holes in them to "'release tension' and run better." But according to the article, there is no science substantiating the value of cutting the holes.

Not sure if one conclusion is that organizations are okay with player discomfort. If this is the case, this sucks for current and future players.
