I purchased this same shoe (different color) in the mall for a much greater price to wear for international mission work.  I was thrilled to find it on amazon.com for less!  It is the most comfortable sneaker I've found.  I had a knee replacement done 13 years ago and this is a gentle shoe on my knees.
The shoe seems to run small.  I've been a size nine for years, but the fit of the 9.5 is perfect.
