I have been searching for a great high impact dance/zumba/workout shoe for YEARS! I workout several times a week and do Zumba at least 4 days. I follow 2 instructors, one is very high impact and implements a lot of hip hop in her class, the other is more of a salsa and latin type of dance class.........this shoe is perfect for both! I am relatively young for knee issues but have had several knee surgeries and a replacement before the age of 35 thus good shoes are a necessity. If you are familiar with Zumba there is a lot of twisting of the hips and knees and you find yourself standing on the balls of your feet, this shoe is awesome for all of that!!! I can wear these anywhere, I am not restricted to using them just for dance, I do a circuit weekly at the gym and can use these for that as well. Thanks PUMA for making my perfect shoe!
