Since my order 30 days ago, I have ordered and received another order. I ordered black the first time, and they were so wonderful I ordered white for the summer. I am diabetic and have had double knee replacements. My feet and back hurt more than my legs. Varicose veins were very prominent in my legs. These knee highs have taken care of all my problems - aches, pains, and fatigue. They are wonderful! I wear them everyday, and sometimes all night. It is so nice to have compression socks that go on so easy. I am hoping you have navy as I wear a lot of navy. Thanks AlphaSole.
