I got these to replace a silvery colored pair of Birks that I'd been wearing for 15+ years.  I'm looking forward to wearing these for many years to come.  I wear Birkenstocks almost exclusively.  I have many pairs that I've worn for over 10 years and they still look good and feel great.  The silver color makes these a little dressier than others, which is nice.  Always comfortable and attractive, Birkestock shoes come in a very wide range of styles and colors.  I highly recommend them.
