I have tried many socks to wear with my boots.  I had given up finding good ones until I bought Dan Post Cowboy Boot Socks at Amazon.  I LOVE THESE SOCKS!  They fit snugly, but not too tight.  They are VERY comfortable.  I've washed them several times and they STILL STAY UP! I would recommend them to anyone wanting socks to wear with their boots that will stay up. I just hope you might find them as comfortable and supportive as I did.
