TLSS TIPS | EP.11: Why Even Professional Footballers Pay Attention to This Small Detail (English Version)

Jude Bellingham, Bukayo Saka, Ismael Saibari, Bruno Guimarães และ Keito Nakamura

These players, all shining at the 2026 Biggest Tournament, have one interesting thing in common.

Keito Nakamura, in particular, unexpectedly went viral during Japan's group-stage match against Sweden. The Japanese winger, who currently plays in France, was instructed by the referee to leave the pitch and change his socks.
Normally, Nakamura wears his football socks rolled extremely low that they barely compress his calves, and it almost looks impossible for him to wear shin guards properly. When asked to correct his kit, he simply tore open the back of his socks, creating large holes before returning to the match.

Why would a professional footballer go to such lengths just to avoid tight socks?

Some players roll their socks down around their ankles. Others keep the socks up but cut large holes in the calf area. One thing is clear, many professionals simply don't want their socks squeezing their calves too tightly.

Ironically, wearing socks too low is technically against the Laws of the Game. Nakamura's case became particularly notable because the referee had reportedly warned him several times before eventually stopping play and sending him off the field to change his socks.
The decision had an obvious impact on Japan, who briefly had to play with one fewer player while Nakamura was off the pitch, leading to frustration from both the player and the Japanese team.

Many football socks are designed with strong compression around the calf. For some players, excessive compression can feel restrictive, potentially limiting comfort during long periods of high-intensity movement. As a result, many players look for ways to reduce pressure around the calf in hopes of improving comfort, reducing muscle fatigue, and minimizing the likelihood of cramping.
For these players, relieving calf pressure isn't simply about style. It's about performing at their best.

But what is the best solution?
Professional footballers have access to unlimited replacement kits. If they want to cut holes in their socks or even tear them during a match, there's always another pair waiting in the dressing room.

For the everyday footballer, however, things are different.
Should you wear short socks instead? That may compromise your ability to properly secure shin guards and reduce protection.
Should you cut holes in every pair of football socks? That certainly relieves pressure, but it also damages the socks, reducing their durability after repeated use and washing.

Ultimately, the choice comes down to personal preference. Whether you prefer traditional long socks, modified socks with calf cut-outs, or shorter alternatives, every player has their own solution.

At TLSS, we constantly look for real pain points experienced by footballers. This is one of the most common issues we hear from players. Instead of forcing players to modify their socks themselves, we believe the solution should be built into the product from the very beginning.
So we asked ourselves a simple question:

"Why not design football socks with the calf relief already built in?"

Tonight, we'll watch Bruno Guimarães and Keito Nakamura face each other in Round of 32.
And hopefully, neither of them will be stopped by cramps before the final whistle.
