In Seattle, there's a Roadrunner Sports now, it's by Greenlake. I haven't gone inside the store but it looks fairly comprehensive. I used to go to the one in San Diego, Calif (they also have a website) and the people were so great! The selection is incredible, the salespeople know a lot about foot problems and running, and you try out the shoes outside and on treadmills. I went from having very challenged feet to being able to run again. Anyway, I can't guarantee the one up here is as great as the one in California but it's worth a try.
