Query: My Birkies and me

Hello all!I received my Birkenstocks as a graduation present when I graduated high school back in 2003. Ladies and Gentlemen, these are remarkable sandals. Amazingly, they are still holding up! They do show signs of wear e.g. some of the cork is looking old and crackly, but they still feel wonderful on my feet. I suspect I'll still get another few years out of them. Note that I mostly wear these on vacations and weekends.I've read other reviews about how the leather upper can cut into your foot. This happened to me the first week or so that I had the sandals. The person and the Birkenstock store alerted me to this, telling me that they needed some breaking in time. She also mentioned that it could give you blisters while the leather softens. Just be patient guys. Like every good leather shoe, this one needs time to break in. Give it some time and the sandal will last you for years.. decades in my case!
