These fit nicely! I wear a 9 1/2 shoe and these do not have to stretch to fit me.  They are not really a true crew sock as it's a plain knit all the way up and some sort of elastic at the top with just a small amount of ribbing.  Real crew socks have ribbing up from the ankle all the way to the top of the sock and do not require a round of elastic at the top to hole them up. One reason I like true crew socks as they don't bind my ankle and cut off the blood flow, worsening my varicose veins.  I'll cut some of the elastic rounds and pray they stay up!
