Ok, I too am a sock freak. I can get blisters that pad my whole foot.
Liners, I upgraded to the patagonia capilene and also picked up a pair of Ultimax liners, they are great and even have a little compression. Yes they are worth the extra five bucks.
I have smart wool everything. Dress, hiking, workout. Not yet tried their liners, although I here they do very well.
If you guys want to buy pm me with size,sock and color. I got sick of paying retial so i created a little LLC to buy my outdoor gear and I sell it to friends at cost plus 10%. You save about 3-7.00 per pair. But you need to order a minimum of twelve pairs, unless we can get others to help. THey have minimum orders.
I have recently tried out the Ingenious Line by wigwam, It is a liner built in to a wool sock and so far I think they do very well. I have used the liner socks with them out of paranoia on heavy workout days. (5+ miles) My feet come out very dry.
