If you wish to rely on "MythBusters" that it can never happen, that's up to you. A half inch deflection can certainly trap someone's foot if their toes are already touching the top of the boot. I've SEEN it happen. If you are giving more credentials to statistics, you certainly have the right to take the chance especially with steel from China. A horse hoof and a woman's foot have about the same sq inch of surface area except on that one foot, a 1400# horse is exerting almost 350# on one foot. Now multiply this by a rearing, stamping horse and then take into consideration if the horse has steel shoes and then take into consideration what part, angle of force and axis of that steel horse shoe does the striking and then take into account if the wearer of shoes is on soft ground or a cement floor. No one here can tell me your feet are 100% protected with cheap, steel toed boots and how that piece of steel is supported within the shoe and my proof is my own eyes. Period. Now everyone can do whatever they want and I shall do the same.
