My husband wears a shoe size 15 and is a EEE -- very wide foot. He feet are like a huge square. haha. Anyway he said these socks fit well and are decent and nice for the price. We use to get the Meijer brand extended sizes which fir him well but for some reason they only sell them in crew style now and he hates those because of his calf's. so these were an over all good purchase till we find better ones.
