I would add the caveat that tall people should consider staying in traditional boots. I'm 6'3 wide-shouldered. I finished the AT and still wieghed about 200 lbs skinny as a rail. With a full pack I had 230 lbs on my feet and that was at my lightest. That is just a lot of weight coming down if I roll an ankle which happened like 20 times a day. I am jealous of the folks in trail runners but I just don't trust them with my frame.
