This basic ballet flat is exactly what I wanted. I wear a 6.5 and bought a 6.5. My only negative is that my size - and many other sizes - are not currently available, so I can't purchase these shoes in another color. The first time I tried them on, I thought they were a little tight, but after wearing for a few minutes, they felt quite comfortable. The description says "navy" but it is such a dark navy that it blends in well with my black pants. The soles have non-skid ridges, so the shoe should not slip on most surfaces. I would not wear these if I had to do a lot of walking, but they are perfect for the office or just hanging out.
