I think you should make a wise investment because you have diabetes, go to a medical supply store to purchase them, they also have an appliance that makes them easy to put on. My husband had to have them after his heart transplant, they are tight and I don't think we could have been able to get them on him without the appliance, but they really did work. Please take care, diabetes isn't anything to mess around with and because it does affect your circulation the good socks will be a worthy investment.
