Merrell, New Balance, and Keen all seem to be getting a lot of props on this thread. I endorse those three brands wholeheartedly, especially Keens, which run wide, and New Balance, which goes the extra mile with width selection. Right now I'm wearing a pair of Merrell Moab Venilators (yes me too), and although the tongues are on the thick side and rub my instep from time to time, they're otherwise very comfortable, seem to be quite durable, and it has been a total pleasure to play DG in them. I got 'em at REI for $85, and I think the Gore-Tex model runs about $20 more. In wet weather I'll wear my Gore-Tex hiking boots.
And as a former REI employee and current co-op member, I recommend you shop for shoes at REI. They sell all three brands, as well as a number of other high quality brands, and the return policy is second to none. Who else guarantees your satisfaction for life? Let me repeat that: there is no time limit on their return policy, even for shoes. If you buy a pair and 5 months later they fall apart even though they shouldn't, they'll still take 'em back and refund your money.
