I wear the mid weight hiker year-round. Depends on how often you do laundry - 7 pairs is enough for me to rotate through. I frequently wear them two times, especially if I’ve worn them on a pretty sedentary day.

I have a couple lightweight casual pairs and they are atrocious. Thin, make my feet so sweaty, they’re tight and they just feel weird on my feet. I also have a pair of no-show but they are slightly stiff.
