I bought these sneakers for my Zumba class - they are ideal for this type of a workout.  Luckily I had read some of the other reviews, and knew to buy a half-size up.  Also, if you have very wide feet, these won't work for you.  They are just right for me, but someone with a wide foot would find these shoes uncomfortable.  I really enjoy the fact that the soles are split, they are very "bendy" but even so, I feel very secure on my feet dancing in these sneakers.  Appearance wise, these shoes are CUTE!
