New Shoes

Options
Hi!
I am in need of new shoes! I would like to purchase a pair for working out. My workouts are usually circuit training/Jillian Michaels/weight lifting with some walking/jogging outside and on the treadmill. So I do not want shoes that are strictly for running--but that would serve for ALL work outs.

I also have started wearing my tennis shoes with jeans for when I am out shopping...so I guess I also would like to know if you wear your workout shoes for your "everyday" shoes as well. I was told by a Jazzercise instructor a million years ago that you should never wear your workout shoes for anything other than working out...so if you know of some great "everyday" shoes, please let me know! Or if that is a total crock, feel free to share that opinion as well!
Thanks!!!
