Luann, I agree that the shoe brand doesn't matter as long as the shoes are well built and designed for the activity (e.g., I don't wear running shoes for step workouts because of the need for lateral movement). I sought out the Ryka shoes worn by Cathe and crew in their recent DVD series only because I was in need of a new cross trainer/fitness shoe. They are comfortable but I would have been just as happy with an Addidas or Nike cross trainer if you've found one that you like. It helps to know the style number. Some months ago I tried a New Balance shoe (623, I think) but found it uncomfortable and returned it.
