That is a loaded question...I like leather lined Norwegian welt boots made by Limmer Boots...others go with a good pair of trail runners, some swear by Hy-teck, Salomon, Vasque, Kayland, Scarpa, Keen, Merrell...or, or, or...It comes down to personal preference really. Brands fit different feet better than others. Some run narrow, others wide. Here is a link to Backpacker.com's online reviews and after that my best advise is to go to stores and try on several different pair and walk around the store and see how they feel. If you choose a pair, go home and wear them around the house for week or so that way you can take them back if they don't feel good.
