I really like the style and color of these Aerosoles.  However, I ordered an 8 (my normal size), AND THE HEELS KEPT SLIPPING OFF AS I WALKED.  The shoe was comfortable, so I found an easy fix by ordering an inexpensive pair of heel grips - called "Profoot heel snugs" for under $5.00.  I really wanted the shoes, and this fixed my problem.  It was cheaper than sending the shoes back.
