Review on Premium Graduated Copper Compression Socks - (8 Pairs) for Men & Women - Enhance Circulation - 15-20mmHg - Ideal for Running, Athletic Activities, and Cycling by Isaac Simpson

These socks are comfortable but don't reach the knee. Rather about the caviar. They are about 3 1/2 inches below my knee. So I needed another 3 inches for a perfect fit. I'm not big either. I am 5.5 1/2 inches tall. I didn't see the size when I ordered it. If you have fat legs, they can be shorter. I don't think I have fat legs :). You feel comfortable and look beautiful. I don't feel like they have 30-40 toe compression. I have 20-30 compression stockings and they are tighter than these. If they were longer and had more compression I would definitely buy them again but not sure at the moment.
