This review is for the BIG BUCKLE Arizona.  I love Birkenstocks, but this was my first pair of Big Buckles.  Five stars for cuteness, one star for comfort.  I really wanted to love them, but they are hideously uncomfortable.  The leather is stiff and rubbed two blisters on each foot the first (and only) time I wore them.  I went to try them a second day, and when my foot slid in, it instantly hurt.  The foot bed is smooth, which was not a problem, and sizing was perfect.  I wear a 7 1/2, and the 38 narrow fit perfectly.  The only issue is the stiff leather, which I don't think is going to break in.  I've got leather Birks and they are nothing like this.  I know that by buying from Amazon, I risk getting fakes.  Two things make me think these are not fakes:  I paid the full $150 for them, and also I'm not the only person who gave them a negative review.  Many people complain about the stiffness.
