This is my first every review for any product i purchased on amazon. I think this pair of shoes should not be up for sale. it is a pathetic product i ever purchased on amazon and i regret it. I purchased it for my zumba class. Today's was the first day to wear them to class and i had to leave the class 10 minutes before the class ended because i could not move my feet any more in these shoes. Don't waste your money. Worst, Worst product ever purchased on amazon.
