I've internet searched but can't find them. Save for the big NIKE on the back and the swoosh, they're fairly plain for Nike standards. I think its something they probably put together and haven't tried to market yet given the change from Reebok
I did find this on another discussion board for umpires-
NFL Referee Shoes - Off-Topic - Umpire-Empire
I've looked at the 1.3's but I don't think the NFL shoes have Nike Air and they sure don't look like they ahve any mesh to them.
