Smartwool and Thorlo are hands down the best, IMO. I wear these year round, in all kinds of thicknesses and heights and in all kinds of footwear. The fit is fabulous and they're very durable, especially if washed and dried properly. (No regular detergents -- use Woolite or an equivalent, and always line dry.) I haven't figured out how to wear out a pair of Thorlos yet.
Wigwam used to have a terrific liner called the Ultimax, but they've changed the construction and I can't vouch for the new version yet.
