@dirtbag:
On my NPT hike I wore Injinji original weight toe socks. 2-pair (doubled up on each foot) and completed the trail, with continuous wet feet, without a blister. YMMV. I’ve been in drier areas been wearing just one layer of their thicker trail weight trail running socks, also to good effect.
@markverber reported wearing xoskin toe socks. These are made with a ptfe fiber matrix. The teflon likely reduces friction as claimed and may be an option to Injinji, and hopefully longer lasting.
All said, definitely give toe socks a try. Wet feet, hot feet, cold feet, and shoes full of sand – I haven’t had a blister since 2009, this on 15 to 20 mile days.
