Oh my Lord! Where is this stuff coming from? The purpose of steel toed boots is to severe the toes rather than crush them? Not likely!
Have any of you guys ever worked construction? Have you ever had anything heavier than a horse land on your toe? Or how about a cutting tool? Steel toed boots are to prevent damage to the toes, not determine what kind of damage is inflicted. Years ago, someone figured out that if something lands behind the steel toe cap, the foot could be damaged, so they put in meta-tarsil plates to protect the upperfoot. So, does that mean that the meta-tarsil plate is there to prevent crushing of the foot, but severing at the ankle? NO! Oh, and what about steel sole inserts? Those must be to localize potential damage to... to... to... to what exactly?
Wow. I'm sorry, but I just am totally floored by the mumbo-jumbo on this thread. Better to be crushed than severed; better to be severed than crushed. The point of steel protection is PROTECTION!
No way can anyone ever cover every aspect of safety. You can wear a helmet and still break your neck. You can wear steel toed footware and still loose your foot. There is no way to put someone in a rubber room, except to actually put them in a rubber room.
