Thanks for all the feedback!

I had originally assumed I'd order the pair of sale boots to start with, then if I didn't like them, take them to REI and keep trying on others. Didn't work out, though, because by the time I went to place the order they were out of my size.

So I went to REI and tried on boots and climbed the rocks and changed socks and tried them again and eventually chose the Vasque Breeze (here).

Thanks for reminding me about sock liners. Does anybody have any good sites for ordering some? I used to have a couple of pair, but can only find a single one now!

And we go to Rocky Mountain National Park, and that's where we're going in a couple of weeks. Can't wait! (I don't consider it going to Estes Park because we tent camp in RoMo as opposed to staying in town.)
