Like everyone said, this store has attentive staff who takes the time to fit your feet with the right shoe. They looked moderately busy when we walked in, but a man greeted us and asked us to be patient. Someone got to us within a couple of minutes and helped both my friend and me at the same time. The entire process was maybe 20 minutes. He gave us great advice about starting to run, too. We then waited a couple minutes at the counter to be run up, but it seemed like they were busier than usual, so it wasn't a huge annoyance.
Don't walk in thinking you'll be looking at stylish Nikes or anything, but you will get great service and shoes that are properly priced.
