Our gym is carpeted and we have about 7 Zumba classes per week at our small ladies gym. The Zumba slips are a Huge benefit to our ladies and they use them all the time. They allow your shoes to slide easily on the carpet and release the knee strain which allows the gals to do those sexy moves with ease and confidence. I Highly recommend these slips to anyone doing Zumba on a carpeted area. They are Amazing little no brainer items to keep the health of the joints sacred!
