Very comfortable!  They kept my feet happy and...while not DRY, they weren't as sweaty as  normal.  I've used these for nice 10ish mile hikes over my compression socks, they provide plenty of cushion and dried quickly when I had to walk through streams.

These socks aren't very durable, after about 7 months of varied use...and in a normal sock rotation they've lost a good amount of cushion around the ball and heel of the sock.

I really like these socks, I bought another 3 pack for my up coming 30 mile hike because I know these socks won't give me any problems!
