I really love the keen socks. For some reason, the left and right design really makes for a better fit. They also feel good on the arch of my foot. This was probably my eighth or ninth pair that I have and they are the socks that I will reach for first. They are rather expensive, so I always watch for them to be on sale. Wait for my review of Elsa II waterproof Chelsea boots! Paired with the these socks...amazing!
