I have bad knees (at age 65) after playing tennis 3 times a week for years. I thought I would have to quit after the first zumba class my knees where aching. got online and bought these. Now having fun at class!
Something so simple made my zumba workout easier! It allowed me to move without twisting my knees out of shape. I recommended to fellow zumba participants if money doesn't allow to buy the dance shoes.
