It states in the 2014 ATR:
5.1 Officiating Team Uniforms .... Black shoes are preferred but referees can wear any color shoes so long as they are appropriate to perform the duties required of an official.....
However, I also read through other various web sites and heard from other refs that only black shoes are allowed and may have white logo/lettering on them.
So, what color shoes can the referee's wear and do they need to match the AR's?
