I have every type of dance exercise DVDs you could possibly think of...have had them for many years.  Recently, I've also begun to enjoy Zumba as well.  I play all my DVDs in the comfort of my own home on my carpeted basement.  I figured that way I have no excuse NOT to exercise.  A while back, I had bought carpet gliders to put on my sneakers so I could easily move on my carpet.  Recently, I saw a video from Consumer Reports recently how not wearing the right type of dancing shoe could really hurt you...your back, your legs, etc. Even though I've been careful and have not gotten hurt, I didn't want to take a chance so I went in search of the perfect dance shoe for Zumba, etc.  After reading a lot of reviews on dances shoes on the internet, it seemed that Nike was the clear leader, with Ryka and Bloch being rated highly too.  However, I've come to rely on all you guys who write your reviews on Amazon.  You get the best and the worst of every product, and even though there are other sites that provides this too, Amazon is clearly #1.  So after doing my homework, I read through every review and decided that these Capezio Women's DS24 Rockit Dance Sneakers had the very best ratings of all the dance shoes.  The majority said they were super comfortable.  So I took a chance and when they arrived, I quickly played one of my Zumba DVDs, then another and another...not only are they super comfortable, but I can now pivot beautifully on my carpet.  My carpet is a thick pile and it has thick padding too.  If I can glide on this carpet with these shoes on, anyone can!  I took everyone's advice and ordered a size 8, even though I am size 7.5.  I will say that the shoes are a little big so I may be the exception to the sizing up rule unless if my feet are shrinking!  But with heavier socks, they are just fine.  I didn't want to send them back to only find out the 7.5 are too small.  They are lightweight, provide ample support, but don't constrict you when you need to move or glide across the floor.  I wish I had bought them sooner, but I figured the carpet gliders on my sneakers were enough.  Not true!  I also want to thank Amazon for giving all of us the forum to say what we need to say...the good, the bad and the ugly.  I rely on Amazon's reviews for 99% of my purchases.  And nothing beats Amazon's delivery.  I ordered the shoes on a Thursday, and they were delivered to me on a Friday.  Now that's excellent service!  If you take any dance classes, buy these shoes...you will not regret your purchase.  I think I'll go dancing now.....!
