I wear size 12.5 Wide shoes and have been through numerous "large" socks that shrink after the first wash and then are just too small. Local stores sell very few options in XL. Decided to give these a try and I'm glad I did. I like the height (just over the ankle joint) versus low cut or no-show, which tend to allow junk into the gaps. I like the material. It's thinner on top nd doesn't have compression areas. It's not overly thick, so if you are looking for cushion or extra support, look elsewhere. I have the same sock in a no-show in gray, but they are size L and are just a little too small, so I knew ahead what I was in for construction-wise. Those have been plenty durable, so it checks all the boxes. I'll be ordering some XLs in black and will keep on the lookout for gray.
