I have used Cabela's outfitter series lightweight boot socks for the last 2 years. They are hands down the best socks I have ever used (day trip hunting or weeklong backpacking). I've never had a blister (and that includes breaking in 2 new pairs of boots with them), and liner socks are not needed. They are a merino wool, polypro, lycra, nylon blend, and great at wicking moisture/drying quick. Only about $9.
