I am a newly converted Birkenstock fanatic! We have lived in Germany the past three years and I panicked that I had been here all this time, and now we are getting ready to leave to come back home to the States, and had not tried Birkenstocks! Once I did though, I was hooked! I went from Birkless to having multiple pairs (ashamed to admit it: FOUR). I love all the support Birkenstock offers. I've never felt anything like it. It is like a hug for your feet! I recently purchased these silver mayari from amazon at an awesome price. I can wear these all day, doing all kinds of activities, with no pain in my feet or in my lower back as I usually get. The mayari style is amazing because it offers you two places to customize the fit. I LOVE the birko-flor material as the inside is so soft and comfortable. I have had no problems with chafing or blisters. Also, the footbed is surprisingly flexible to make for great walking. Like I said: a hug for your feet! You won't be sorry!
