For other hikers who use trail runners instead of boots, I am curious what type of socks you use? I am not so much interested in brand as style, material, thickness.
I transitioned from boots to trail runners about 7 or 8 years ago and have never had blister problems until recently, but have gotten blisters under my toenails on two of my last three hikes. While searching for info on this, I found a post (if you read it on the internet it must be true, right!?) that said that one cause for this is wearing too thick of socks. Presently, I still use the thick Smartwool hiking socks (and liners) that I wore when I was wearing boots. So I am wondering if I need to change to a different style/tickness sock for use with the trail runners. I am a bit reluctant to change things up that have worked well for (most of) 7 years, but, as I said, on two of the past three trips I had blister problems. I am used to blister-free hiking and want to return there!
