I haven't worn two pair of socks for hiking since the 70's. That is about when I started wearing running shoes for virtually all of my trail hiking. I did wear two pair of socks when I stopped to put on my climbing boots but that was mostly because I did a lot of ice and snow climbing. I now wear one pair of Smartwool light-weight or mid-weight socks with my trail running shoes. Sure my feet get wet on occasion but they generally dry quickly. I think you will find that trail runners and one pair of fairly light socks are the norm for people on this site.
