I am not sure which division you are from, however I was told that the shoe didn't matter so long as it had safety (steel, alloy or composite) toe so that you do not accidently crush your toes with a electric pallet jack.
I have went though 3 pairs so far. I mostly buy sketchers like these, but with different color variations. I have had black and pink and black and blue. Some associates at my store have steel toed boots, however with the amount of walking you do made me want just regular tennis shoes but with a safety toe instead.
