Carhartt Men's Force Performance Work Socks 3 Pair Pack

Q: What shoe sizes are the Large socks going to fit?

I wear a size 10.5-11 shoes/ work boots and they fit great, the heel part actually wraps around the heel and it doesn't feel or look like they are pulled or loose at all. I would even go as far as saying that they probably fit a range from 10-11 size shoes/boots

Q: Where are these made? Why can't we search made in usa anymore Amazon??

I think these are foreign made, good quality for a lighter sock, but pretty sure they's make it clear if they were American made. Would be nice to be able to search based on country of manufacture, can't tell you why we can't though. Probably due to whining of supposed discrimination & threats of lawsuits, but can't truly answer that part for you.
