WHITINMen's Steel Toe Slip Resistant Puncture Proof Construction Safety Work Shoes

I got my shoes today and the top of foot, is touch to steel toe. Is it by shoe design company? Does anyone feel hurt/pain with steel toe?

How long do these shoes last before holes and rips?

Do the soles leave scuff marks on floors?

Will these prevent a puncture if I step on a nail sticking up through a board?
