Why do footballers cut holes in their socks?

You may have noticed throughout the World Cup that many players have holes in the back of their socks.

And no, this isn’t a coincidence nor is it an accident, better performance on the pitch is the reasoning behind the holes.

See, football socks at times can be quite a snug fit, they can prove to be restrictive and potentially cause problems with effective blood flow and circulation.

The holes help reduce tightness and release the pressure on your calf muscle.

Which ultimately helps prevent fatigue and potential injury.
