Sorry but these are not extended size nor are they crew socks. I like the brand but the socks are horrible. I buy for a size 12 EEE foot. This socks shrank down to size 9 and he cant get the sock on his foot. The socks are too long as well. My husband is 6’2, these socks touch his knees when they should be only halfway up the calf like crew socks should. Not buying PRL socks until they fix this problem.
