Rating : - Quality Sock I bought these to run my order up for free shipping. The choice was pay $5 for shipping or $7.50 for socks and get free shipping. I thought they were a bit expensive. I used to buy Hue OTC (over the calf) socks but they have stopped making them! When I received these socks and saw the quality I was impressed. They are very comfortable. They are worth the price. I just wish they would bundle them in packs to give a quantity discount, but I will spring for these again...
