Like Cinderella I was hoping to have these not fit quite so tight.  they were listed as 5 and one half to 8 and one half.  My foot is a 9 ish,  wishful thinking on my part that they would work.  they fit on my foot a bit snug and after a significant amount of walking it stressed the sock too much and toes began poking thru.  I just wish there would have been a choice of a larger size, I really do like the socks.  Really great when at the airport and have to remove shoes the non slip cotton bottom protects one's feet and looks classy.
