Up until recently I have worn rigger type boots made by a french company called Jallette, they are extremely comfortable and have a stainless steel plate in the sole to prevent nail ingress etc. I have recently bought a pair of Dewalt boots to see how they shape up. I always feel "naked" if I am working without the protection of the steel toe cap boot maybe it is due to the fact that I have worn them for over 25 years.
I have worked in a lot of establishments that will not let you wear steel toe cap boots if the cap is at all exposed, due either to design or damage to the cap cover, this is on petroleum, ordanance and chemical installations to prevent the chances of a stray spark being generated by the steel contacting another material
