There's so many good things about socks.
Unfortunately most of their lives are spent stuffed into your boots from the last time you used them. You'll spend about 15 minutes looking through your drawers for them, before you eventually find them in your boots, still sweaty and super stinky. With an hour to go before the game you've just got to wear them because you don't have a choice. You'll go through this process many times despite vowing to never do it again.
These ones come branded with the club name down the side and are a requirement for all players to have.
For an unlimited time buy one sock, get one free!
