This was my first ballet shoe, purchased for a barre class at the Y.  (I'm 59, but never had an opportunity to learn dance.)  I absolutely love it!  Based on Capezio's fit guide, I ordered the same street shoe size that I actually measure on one of those measuring devices at shoe stores.  Capezio's fit guide seems to work very well for their dance shoes; I own 2 pairs of their character shoes - perfect fit first try, both times.  (Due to the variance in manufacturers, and even shoes within manufacturer, the size that I measure is frequently not the size that fits, and I seem to have very hard to fit feet.)  These fit perfectly!  Even the width is perfect, and I generally have a terrible time with shoes being too wide.  They're soft & flexible; when I move they move with my feet, and I don't go sliding around inside them.  They're as comfortable as being barefoot!
