The socks are nice and comfy but I found the tops rather loose so the socks slipped down as I was walking in my shoes.
I'm not a diabetic but have developed a heart condition, and nomal socks are beginning to make an indent round my ankles, which get slightly swollen by the end of the day. It's a fact that these socks don't leave a mark, and in my opinion miraculously manage to stay in place and not bunch up towards my toes as i feared, since they are so stretchy that the heel can be pulled up almost to my ankle when I put them on! (Yes, I got the ones that are supposed to be my size!) So for comfort i would recommend them, but not for appearance. And i wish there had been some colours to choose from other than Blah
