This pair of Carhartt steel toe sock was purchased for my grandson because he kept getting blisters from his boots.  They fit my size 9 boot foot really snug so I thought he wouldn't like them for his size men's 9 boot, but he wears them all the time, he said the snug fit keeps them from bunching up around his toes and has helped with the blisters.  Now he needs more than one pair of these, because the steel toe socks he has from Thorlo don't help as much.

I'm also thinking of getting a pair for myself, the fit was great, Grandma wears boots too.
