From experience and other reviewers I ordered half size up and I have a comfortable fit.  However, I should have stayed with my usual width of narrow (2N) and not medium (B) because it feels a little loose, but that is my fault.  I love how flexible the shoe is and even though it is a medium fit, it looks neat and narrow on my feet.  I am very thrilled that &#34;Easy Spirit&#34; has kept up the standards of their products and I will give updates about usage as time goes along.
