Does anyone here know the rules on shoes? I hear about 50 different things!! Im a 7 year employee and i hear different things all the time and now its a big issue once again with our shoes on preload! I have an upper leather nice sturdy slip resistant Nike shoe. I had Under Armour which were just the same! They gave me hell about the UA and now they are saying the Nike's are unapproved also!! Can someone please help without the smart comments, please? Thanks!
