      Also the best socks I have owned - 10/13/2014
      By: from Minneapolis

      I am a sock fanatic. I have specialized socks for hiking, backpacking, biking, snowshoeing, cross-country skiing, kayaking, etc. Each is specially suited for for certain aspects of their use. These Invincible Extra socks are for everything else. I have purchased a couple dozen pairs of these socks over many years. They have padding in the right places, they stay up. Just don't pull them up by the elastic around the top. Reach a little lower to pull them up and you'll get great life out of them.

      Great Socks! - 10/7/2014
      By: from Boston, MA

      This is arguably one of the best pairs of socks I've owned. They're not too think but have decent cushioning and are very comfortable and decently warm. I would but this again when I'll need more and so should anyone who is looking for great fall socks.

      Good Product - 10/2/2014
      By: from GA

      Invincible socks feel good, wear very well, and don't snag. I use them for motorcycle boots, hunting boots, cowboy boots and sneakers. This is my second order; not because my first set wore out, but because I wanted more of them.

      Best sock in the world! - 6/5/2014

      This is the only sock I wear I've been wearing it for years and I don't expect to change. It is a sock I give as a gift, enough said.

      These appear to be on the mark. - 5/27/2014
      By: from Rural TN

      The socks appear to be on the mark. They can be donned without a herculean effort. The tops stay up nicely. I've had them for only a short time, but if they wear as well as their predecessors, they will be long lasting.
