We found these looking for slip on shoes to work in the basement and shovel snow.  The steel toe is certified for work - so he can put them on in the morning and not have to change into boots when he gets to his mechanic's job.  Saves wear and tear on the old bending back!!  Price was good and check if your work offers a refund for purchasing your own safety shoes - his does!
If I could give it 100 stars I would.
