Footballers cut holes in their socks primarily to reduce pressure on their calf muscles caused by the tight-fitting nature of football socks. This practice helps to relieve discomfort, improve blood flow and circulation, and prevent muscle cramps and fatigue during matches. The holes allow better ventilation and freedom of movement, which can enhance performance and comfort on the pitch. Many top players, including Jude Bellingham and Kyle Walker, have adopted this trend as a way to gain marginal physical advantages and avoid injury risks associated with restricted blood flow or muscle tension.
