As a long time runner, I invest in great shoes and a professional fitting. Recently decided to Zumba, loving the freedom and intensity of the movements as well as the community of class (go WestSacZumba). I thought Zumba to be more dance and less athletics. I bought several shoes (dance sneakers and tennis shoes) before coming across this one. I was very skeptical and sice I have wide feet (quack quack) I was hesitant to buy. I am usually a 7D and bought 7.5B. I love these shoes. The sole of the shoe has traction spots in the same place as the "real" zumba shoes and as a result my ability to master the movements has gone up dramatically. Also, knee pain I was having is gone...allowing me to step up the frequency of class. Prior to wearing the shoe I thought the whoe "Q Angle" thing marketing whooey. Now I'm convinced.
