A quick question about camp shoes. Are they worth it? I can survive with wet trail runners for a 2-3 day trip, which is normally all I have time for, but am planning an AT thru hike in the next couple years and was wondering if they are worth the added weight for longer trips. I discovered unshoes and I can get a pair that isn't a flip flop (hate flip flops) that was about 3 oz. Thoughts?
