This article reveals the scientific reasons why many football players at the 2026 World Cup choose to cut holes in their socks.
At the 2026 World Cup, one image has appeared repeatedly in nearly every match: many players step onto the field with socks that have holes around the calf area. Social media buzzes with various theories suggesting this might provide a competitive edge. However, this behavior is not new; it has been observed in football leagues, European championships, the Olympics, and other international competitions over the past decade. Yet, to date, science has found no evidence that cutting socks actually enhances performance.
If we look closely,professional football socksare specially designed to fit snugly around the leg shape. Besides holding shin guards firmly in place, they support the ankle, arch, and calf, control moisture, and reduce foot movement inside the football boot to improve stability.
This sock design principle has been used in professional football for many decades. Although materials have evolved to be lighter and more durable, synthetic fibers like polyester, nylon, and spandex remain the primary components.
However, quite a few footballers complain that the socks feel too tight, causing numbness around the calf. This discomfort can become so severe that some players cut multiple holes in their socks mid-game to "relieve the tightness" and move more freely.
This phenomenon involves biomechanics: during sprinting or sudden changes in direction, the largest calf muscles contract and thicken to propel the body forward. This shape change happens thousands of times in one match. For some players, this repeated expansion is enough to make them feel the pressure of tight socks continuously squeezing their calves.
Over time, cutting holes in socks has become an almost instinctive explanation among players — slicing the fabric to allow muscles to "breathe" more easily, which helps relieve pressure and reduce pain or cramping.
However, sports medicine and rehabilitation experts point out that no studies have proven that cutting holes in socks actually provides benefits. On the contrary, most research on compression garments shows that when properly designed and fitted, such clothing can even help limit muscle inflammation after intense exertion.
Despite the lack of physiological evidence, this practice remains widespread among professional footballers. Nowadays, it is viewed more as a personal experiential phenomenon for each player rather than something scientifically proven. Moreover, competition rules do not prohibit modifying socks, as long as the equipment remains safe and shin guards are properly covered.
With no scientific backing, many experts believe part of this phenomenon can be explained by the athletes' own perceptions of comfort.
In elite sports, feeling comfortable can influence a player's confidence during competition. If a player believes a piece of clothing is too tight, removing that perceived discomfort might make them feel freer when running, accelerating, or changing direction — even if their actual performance does not change.
Although there is no evidence that cutting socks provides a competitive advantage or lowers injury risk, the discomfort players feel is not imaginary. Perceptions of pressure, tightness, or comfort depend on many factors, from individual anatomy and sensitivity to past experiences unique to each athlete. In other words, two players may respond differently even when wearing identical equipment.
