Can referees wear Grip socks?

[@robpealing1878]

I’ve worn grip socks for the last couple of seasons. Find them brilliant, particularly as an assistant. You can buy Nike stirrup socks that hide them too.
Plus I find Lux are the best brand with a 1 year warranty for free replacements

I think they are a game-changer to be honest! I am thinking of getting a couple for pairs for when im training!
