These socks are great. I have socks from Icebreaker, Smartwool, Stoic and some of the off brands(Kirkland, etc.). These are the best by far. Merino socks are nice anyway because they breathe well and I don't get blisters, but I have found durability issues in some brands. Not Icebreaker. These bad boys have held up well after many miles on the trails.
