I love my Birkenstocks. I really do. They are the first thing I put on in the morning, and the last thing at night. I loathe rainy days, and snow, as those are the times I cannot wear them out of the house. Otherwise I throw on a thick pair of socks and I'm good to go.
I'm on my third pair. I bought my first pair, purple, when I was 21, during an excursion to the "hill" on the SU campus. I bought my second pair, brown, when L was a newborn. Even when my big toe wore a hole in the front, I wouldn't stop wearing them. M finally bought me a new pair, black, for Christmas this year.
I once broke my ankle in New Orleans. I don't think I would have fallen if I had my Birks on. M changed from his dress shoes, and into his Birks for our wedding reception.
Did I mention that I love them?
