I love these dance sneakers.  I bought them for Zumba Class.  It's much easier to do the steps and they make me look better than I am.  The sneakers glide easily on a hard floor and are very shock absorbent.  I usually wear a street shoe of size 7 1/2 and a size 8 for sneakers.  Going by their drop down which converts to USA size, I ordered a Size 10 and it fits great. As other reviewers mentioned, you need to carefully review the size conversion.  Great sneaker at a great price.  I also wear them practicing in my living room on rug which works fine and your feet do not get stuck which could damage your knees.  I may even use these for ballroom dance lessons.
