Welcome!
I’ve always used A&H International: https://referee-equipment.co.uk/
Don’t worry about white-top socks. That’s very VERY old school.
If you’re part of your local RA you get 10% off at sporting touchsorry, stupid question.
where is the best place to get a referees kit? also, I have heard that some people say the socks need to have a white band at the top. All refs' socks I have seen online are all black.
Their cheapo Sondico plain black socks are comfy as! Four pair of those for £11 sees you right through a season.Sports shops (like sports direct) do cheap back up socks, like 2 pairs for £5.
