These shoes are painful to wear as the upper lip digs right into the front of my ankles cutting off blood flow. I'm a chef in a restaurant and it's incredibly difficult to work fast in these shoes. The only reason I didn't send them back is because I got them dirty within the first hour of wearing them and I didn't have spare shoes to change my shoes. I might even cut off my upper lip entirely because it's so inflexible. You have been warned, DO NOT BUY THESE SHOES.
