Can socks have a PhD?
I have to warn you that if you are outraged at paying $15 for a pair of socks many times over the course of your lifetime you should not even try SmartWool's Phd running socks.
They aren't exclusively for outdoor atheletes. The socks are lightweight and made of Merino wool. Cotton socks are warm and itchy, synthetic socks are cold and clammy, and wool socks keep your feet cool and dry.
In my experience these socks wear out extremely fast. That's the one trade off. Expect holes and the material of the wool to wear much faster than cotton or synthetic. Still, the comfort won't compare with synthetics.
