It sounds like you made a really good choice. I think cross trainers or walking shoes would both work well. One of my criteria is that they have to be very lightweight, as I said, I hate to wear shoes, so the weight makes a big difference for me, not only in the way they feel on my foot but how well I perform in a class because of how my feet feel. I think Ryka's are still made. I'm a big water aerobics person and they make shoes specifically for water aerobics, but are very expensive.
Good luck! Let us know how the NB work for you when they come!
