I need to find a chef shoe or non-slip shoe for a size 15, 3E WIDE? I really need the. Any suggestions where?

That is a tough size to find in stores! Try on line. Zappos probably has the best selection. They ship for free both ways, so order a few pairs and send the ones you don't like back. They are more expensive than a lot of places but have all different price points. Good luck! And get a good quality pair. You'll be happy you did. Good luck!
