This pair of shoe is very comfy in the very beginning.  The only problem for me is the strap on top is still tight.  My feet cannot get in completely.  My feet is not particularly wide or fat.  It is true to its size.

Update 10/9/2013: actually I threw it away after 2 week.  I wore it 5 days in a row in the first week.  However, I started to feel pain on my 1st & 2nd Metatarsal area on the 2nd day.  I did a lot of walking on the 1st and 2nd day, therefore, I thought it was because my feet were tired and which was normal.  In the 2nd week, I started to wear it once every 2-3 days only and the pain persisted.  After 2 weeks, my heel was so sore that I was limbing badly for a week after.  It's been 4 months, my heel is still very sore when I am walking even with a pair of expensive insole.  I remember that I saw a warning label which came with the shoe saying that some people might experience foot pain and they should stop wearing it.  I am not so sure if I am the lucky one.
