I second (or third or fourth) the "try 'em on" recommendation. Feet vary! For me, I have absolutely flat feet - I was born without arches. Anything with a very definite arch hurts like anything.

I love my Vasque Sundowners and my Danners. Especially the Danners, though they haven't been as durable. On the other hand, I have friends who found both brands way too narrow and not supportive enough. Not to mention boots vary even within a brand - some Vasques are much too bumpy inside to work for me.
