I tried Zumba for the first time this week. It was fun and I think I want to do it some more. The biggest problem I had (other than my complete lack of coordination) was that my shoes were "sticky". My "gym" shoes are a pair of Avia running shoes and every time I would try to pivot or slide they would stick solid. Can anyone suggest a specific pair or type of shoes that will allow me to move on the floor easier? Do they even make "aerobic shoes" anymore? Oh ... and I really don't want to spend more than $40 on a specialty pair of shoes for an activity that I may not continue.
