As the founder of XLfeet I wear size 16 and depending on the shoe or boot, my width fluctuates from EE to EEE. Wore these socks while ice fishing and snowmobiling in Hibbing, MN(Northern Minnesota near the Iron Range). My feet were cushioned, warm comfortable and dry the entire time. I was concerned at first that they would not fit over my calf, but there was no issue. They went on easy, offered a generous stretch, and at the end of the day, the sock looked just like it had when I initially put it on that morning. These socks do not stretch out over the course of the day and get "floppy" for lack of a better word. If you are looking for a premium Merino Wool sock that comfortably fits a size 16 EE or EEE foot, the Darn Tough Mountaineering Over-the-Calf Extra Cushion Socks in my opinion, are the best socks out there.
