Personally, I've always worn them...they've saved my tootsies a number of times. As for the OP, you need to get with your personnel safety (EHS) person to determine risk and get their input. It is a PERSONNEL SAFETY issue, and not a health issue.
All those who say they do more harm than good are not using the appropriate footwear for their feet. It took me 10 years to find footwear that met my needs and I went through a myriad of iterations, but I've finally found them. To all those with foot problems go find the footwear that works best for you...your feet, and rest of your body will thank you.
I'll also say that losing a lot of weight helped immensely...not calling anyone fat here, but take this into consideration because every pound makes a significant difference to your overall body, back, knees, feet. And generally on the footwear the lighter the better...pay the premium to get a light shoe with a composite toe (if safety toe needed).
