I have a pair of these, though I only need to wear them occasionally:
They have got me through site safety training at work, where the person running the course treads on your toes to check that you are wearing steel toe-capped boots.
I own a pair of those, the model name is Palladium Baggy.
They are both comfortable and good-looking, but are quite useless during fall/winter (which is the season when you actually need work boots): being one layer of canvas, they don't give your feet much needed warmth.
Wearing two pairs of socks might help.
UPD: And they are certainly not steel-toed.
