I LOVE LOVE LOVE Birkenstocks.  I just plain wore out my last pair, so I wanted to try a new style when I got a new pair.  I love the style of these and they are SO cute.  Despite reading some other reviews that they are heavy, I ordered them anyway.  After all, I am a Birkenstock girl, I know how they are heavy, that is why I like them.  The support is amazing.  When these came I wore them around the house and really tried to convince myself that they would work, but I just couldn't.  The flip flop style just doesn't work with the heavy cork footbed, unless you want to grip really hard with your toes all day long.  I returned them and got a different style, that I love.
