Great liner, very durable
These were more an experiment than anything for me. I almost exclusively wear Smartwool's trekking socks while I'm backpacking. I gave these a shot with some other sock combinations to see if I liked them... and I do. It turns out that I actually prefer to not use liners, but of the four or five types of liners I tried... these were easily my favorite. They are still occasions where I still use them, and when those times come around I always find myself impressed with how comfortable and durable these are.
If you prefer liners with your boots and socks... give these a shot. You won't be disappointed.
