I usually buy reebok or Avia aerobic shoes , I have taught step aerobics and low impact and am very picky with my shoes.....they are replaced every 6 months at the most......as it happened I needed a pair fast....this shoe was the only one with a review by a instructor.....so I decided to try it....it fits well and is flexable  as I now do Zumba along with step and interval training....I am, used to a high top and it tool me a few times to feel comfortable with the shoe but it works well, gives nice support so all in all I'm pretty happy with it and would buy it again.......
