I love Birkenstocks, and these are the best summer shoes.  They have amazing support, so my feet never ache in them. They actually kind of massage your feet. They're kind of chunky, but cute with shorts or casual clothes.  One thing - If you're clumsy like me, you might find the lip around the shoe to be annoying.  I have caught it on things and tripped more times than I like to admit.  Besides that, these are the most comfortable sandals that I have ever owned and the cost is totally justified!
