Hands down the only sock I will ever wear. I own several pairs of this sock simply because it is an excellent investment. These socks last for years if taken care of propperly. I bought my last pair back in 2012 and they are still working just as good as the day I bought them. They still hold tight to my leg and do not slip down into the shin of my ski boot. I also am a huge fan of the elastic on the foot arch. It prevents the sock from bunching up and ruining a day on the hill.
