I know I'm not the only one who feels this way too. I've worn wool socks for years, and generally find them to be pretty comfortable. As well as being really warm. But wool sweaters (and I'm unsure of the type of wool in the socks and sweaters) are too itchy to wear too close to my skin. I've had many pairs of wool socks that were comfortable, and several wool sweaters and shirts that were scratchy to rule out one sweater being the cause. The homunculus shows the feet have many more nerves than the chest that carry the sensory information to the brain, which means my feet should be uncomfortable way before my chest is even if things aren't that way. What gives here?
