I only have a couple of pairs of alpaca. They are heavyweights. Reserved for very cold days with long sits...IDK about them for walking/hiking...they are extremely warm. I would like to try some lighter-weight versions. Otherwise, I wear 70% or more merino wool socks.
I have a set of alpaca insoles, too. With those and the sock, 200gr boots feel like pac boots without the bulk.
