They’re also just generally more comfortable. Wool insulates even when it’s wet, so if your feet sweat (or you step in a puddle) you don’t get that awful clammy/moist feeling in your shoes. Wool socks come in varying weights so they won’t be too warm if you choose the right ones. I traveled to India for a week long business trip where the temps were regularly over 100 F and wore thin wool dress socks the whole week. I was never uncomfortable and they never smelled (took several pairs and washed them several times in the hotel sink over the course of the week).
