I have very flat feet due to accessory navicular syndrome, and a somewhat bad case of plantar fasciitis due to being overweight.  After having my second child, I returned to working out regularly and it was very painful on my feet.  I tried these shoes out several times in various aerobics (step, dance, kick-boxing) and the first few times my foot would go numb, but after adjusting the laces, I have found them to be very comfortable and supportive.  The roll-bar is amazing - I feel the difference more than any other supportive shoe I've had.  The cushioning is also very good.  The only complaint I have is the shoe is ugly.  It's all white in an age when workout shoes are colorful and crazy and especially in a shoe like this (most support shoes have a wedge look that is clunky), would it have hurt NB to make an effort to offer the shoe in more up-to-date color styles at least?  But still, the lack of pain and support is worth having the ugliest shoes at the gym.
