I love Bloch ballet flats.  This is my third pair and I've never been disappointed: buttery soft leather, sturdy soles (capable of being re-soled), lovely colors, amazing fit.  I wear a 7.5 or a 7w and the 37.5 fits me perfectly.  The elastic around the rim of the shoe is really great and helps the shoe fit snugly to your foot.  I have them in mandarin and it is just about the prettiest coral color I have ever seen.  There is no debating, ladies; order these shoes!
