I wear what I feel is necessary for the "task". Sometimes trail runners and other times something else. Fit is number one though, and sometimes it takes some mileage to show that something will work for me. I would love to wear approach shoes for a number of my little adventures, but good luck finding them in a comfortable 14 eeee.

The Zappos option for online purchasing seems to work very well. Just keep track of the returns and let them know ASAP if they short you. They seem good about correcting errors as well.
