Can chefs wear Dr. Martens?

At my school we have to wear chef shoes (leather, slip resistant for grease or anything on the floors and tough enough for when we drop our knives). I have chef shoes but they hurt really bad and no one in our school wears them due to that, and they constantly untie themseles. I just got my Dr. Martens a but ago and was wondering if I could use them instead? They don't hurt, are actually harder than my chef shoes and won't untie. Can I wear these in the kitchen? Pls only answer from personal experience, thanks.
