Birkenstocks are my favorite brand, and these did not disappoint me.  I bought these to wear with jeans for the winter, since I have all sandals or boots in my wardrobe.  I love them.  They are fairly stiff at first and you have to wear them around the house for quite a while to get used to them and get them softened up, but once they are broken in, they are sooooo comfortable!  I love the Tobacco Brown, too.  Treated them with Mink Oil so that they could withstand the wet weather here in Illinois, and I love the color they turned out.  My favorite pair of shoes!
