Working as an HP/RP in a NPP will require safety toed shoes , either steel toe or composite toe as the illustrious RDTroja (👏👏) stated. There may be NPP which do not allow a sneaker model to be worn in the workplace, but I am unaware of those. The day of the "defined heel leather upper" footwear seems to have passed, at least in my scope of the industry. I have run across sites which will not allow an open weave upper in a shoe model.
That all said, an applicable hard toe has an excellent chance of being acceptable.
One item for consideration will be if you want to wear them in and out of the plant, or if you'll change in and out of them. If you will be wearing them in and out, steel toes and steel shanks will alarm the security detectors and you will remove them and process through security in stocking feet.
