Ordered 2 pair of XL LONG SOCKS AND GOT 2 PAIR OF 3XL. chatted with someone on line to explain the situation and was told that it was a sku error and that the socks were an XL. When i put one on the sock kept creeping down my leg and would not stay up. When asked about returns i never to this day got a response. Poor customer service. To bad because i like the socks and they work well. If you can get the right size sent to you. What a waste of money. Never again.
