I have tried regular tennis shoes for my Zumba class and I didn't think a Zumba shoe would make a difference but I decided to order a pair of the Zumba Women's Z-Kickz Dance Shoe and what a big difference.  The Zumba Dance shoe was so light and flexible that I don't how I did Zumba in regular tennis shoes.  I was able to move more easily in these Zumba shoes that I will only use these for my dance classes.  I am so happy with them.  I might order another pair just in case these wear out then I am covered.  Thank you so much.
