I am starting soon as a preloader. I bought these new balance shoes as they are black, leather, and have a slip resistant bottom. The box says they are part of the NB Industrial line they sell. I have a proper pair of boots coming soon (I wear a size 14 so shopping in person is difficult). Are these acceptable or will my supervisor send me home? I have searched other threads and seen people saying they are fine and others saying they are sneakers and therefore not allowed.
