Thanks for the replies. One problem I have is the odd shape of my foot. It's wedge-shaped, like a hobbit's. The front is extremely wide, but usually by the time I buy shoes, wide sizes or not, that fit my foot in the front, my heel is rattling around in the back, which can lead to blisters. Right now I have a pair of cheaper ($50) Columbias which are fine for walking around at work, but they have this problem and I wasn't too hot to "trail test" it. I've had a miserable time or two and even have a scar in one arch from a blister.
