These are the best socks that I have ever used and I love them dearly. I do not have diabetes but I have very sensitive feet and I need a lot of circulation due to my work in which I do a lot of sitting and standing throughout the day. These socks have no binding but still they stay up and don't ever fall down which can be uncomfortable. They are so very soft to wear and I like to wear them at night too when it is cold. My legs and my feet are allowed to keep their circulation while wearing the socks and I have never had any problems with foot sweat but these socks keeps my feet 100% dry even if I would ever get moist feet.
I purchased my socks at Walmart and I find it to be great that they carry them. They are a bit pricey but then again they last wash after wash. I now own 4 pairs of these socks all in white color, but soon I am going to purchase the black ones too since I like that color better with shoes and boots.
I also have to add that I bring these along when I travel. I travel between the US and Europe and I usually do that in the summer time, so I carry these socks with me in my purse and put them on when I am on the plane. It can get really cold inside the plane and I fly for more then 8 hours so these socks are a must have for me.
