I bought these two years ago, and wear them pretty much every day in the summer.  These still look almost perfect.  I have a wide foot, and usually wear a 9.5 or 10 in Clark's (11's in the Artisan), and the 10 fits like it was made for my foot.  These did require some breaking in to stretch enough to be comfortable, but it was very worth it. (I wore them around the house with thick socks for a couple of evenings).  They have not stretched any further.  They stay on your feet securely.  The heel is just enough for a little height but is not even remotely uncomfortable.  I looked at these again to see about getting another color for this summer!
