Are Smartwool socks available in lighter, thinner weights? I have some really thick Smartwool socks that stand in for slippers around the house, and I like their hiking socks (for hiking), but I haven't seen their socks in a lightweight version that isn't gearish or sporty, IYKWIM. I was looking at some of their offerings online, but of course you can't see/feel thickness that way. Any recommendations of specific styles of theirs?
