I really loved these.  They are not only super comfortable, but I wore them all the time for over a year.  They were still comfortable although I did use a sport insole inside.  But the held up to a lot of wear and tear the stitching held up perfectly.
I gave them to a poor Thai dude that didn't have any shoes, when I left Thailand in March 2013.  He's definitely still wearing them.  Two thumbs up for sure!!!
