Allow me to give some background information to setup my question.
I've been backpack camping for years. My typical trip is a 4 day 3 nighter with a ~45# pack. Hike 3-7 miles, setup a base camp, day hike during the day. 2 trips a year... always the NC mountains. For the last 10 years I've worn an Asolo Fugitive GTX in a size 10. I prob could use a 10.5 but they have been fine for the last 20+ just a little snug. They also either need to be repaired or replaced as the soles are coming off.
I am a distance runner. ~100-130 miles a month. I run in Saucony Triumphs in a size 10.
This year we plan on doing a totally different trip. We will do a 29 miles section of the AT. Amicalola to Gooch Gap with a few detours over tree days. I'll be going out with a 22-28# pack. So a little less than 10 miles a day.
Now the question. New boots? or Trail shoes?
