5 star comfort, 5 star quality, 5 star fit and feel!!!! These socks are backed by a lifetime guarantee. You wear them out and drop them off and pick up a new pair and off you go. That's it, no catch! Love these socks. I have about a dozen pair everything from super soft to thin ankle socks. They are perfect for any activity. Must try them to understand what you've been missing out on all these years. The team at Great Lakes Outfitters will be happy to set you up with your first pair. Trust me, they are worth it!
