These are awesome.  LOVE my Birkenstocks, they are my absolute favorite and I wear them everyday.  When my daughter got married, she even told me that I could wear them to her wedding, I didn't but I sure thought about it.  I love them.  These are great, and I love the color, they are a slate blue, and go great with my jeans.  I never get tired of these and the Boston style is fabulous.  They are leather, so they will last a long time.  Perfect for me.  I would buy over and over.
