These don't fit me properly. They are at least a couple inches shorter on the leg than they should be and the pictures suggest they would be. I do have larger than normal calf muscle but I bought the largest size (I wear a size 13 shoe) and expected that both the foot and leg parts of the sock would be increased in size. I have not had them long enough to know how durable they will be but when I fist put them on I noticed the when I stretched them over my foot that I could see my foot through the sock. They do feel comfortable on my foot and since they're so short they aren't high enough up my leg that they cut into my leg. They stay put on my foot and on my leg. They haven't rotated around my foot like some other socks do when I rest my feet on my ottoman. Once they slipped off the inch of calf muscle I'd been able to pull them up over they stayed in place comfortably. If you're not looking for a full length crew sock and don't mind the sock not covering part of your calf muscle these might be right for you.
