I've been wearing New Balance for years but they just aren't making shoes that are supportive enough. I had read the reviews for this model of ASICS and decided to try it. I normally use the blue Superfeet inserts for arch support and when I put them in the shoe, it felt like heaven. I love this shoe. I've worn it for a variety of cardio classes - from fit ball to cardio sculpt - and they are great. I highly recommend them.
