I don’t intend this as a review of any specific sock, though I’ve already come to rely on Stance Socks. I only want to highlight a key feature of knee height wool socks.
While it’s only an extra few inches of wool, knee-height adds significant warmth. It’s a magic-bullet layer of insulation that boosts overall warmth, while adding zero bulk to your torso.
Though each sock covers only an additional five inches of skin, it’s special skin. It’s your extremities. So, in covering 20% more of each leg, you’re shutting down 20% of lower-extremity body-heat radiation. Stated in the inverse, you are increasing heat retention. Think of the difference a turtleneck makes. Same difference, even more so.
Really, it’s like adding a Capilene 2 long-sleeved thermal top — but adding neither bulk nor fabric-on-fabric friction to your torso. Magic!
