Any advice between the gizeh and Arizona?
First. This is my opinion, second I love Birkenstocks.
To me the Gizeh, Mayari, Madrid, Molina, Relax 100, Sparta, Almere, Yara, Ibiaza & Sydney are more feminine than the Arizona.
They are way easier to choose the right style.
Orginally the Arizona was made for guys.
I choose the Sydney (which look likes the Arizona) before the Arizona. Again much easier to style.
That being said, the Arizona is more like "the boyfriend jeans" of The Birkenstock.
You have have to think if it fits with your clothes.
In my eyes, Arizona works with certain clothing styles, and als depending on the Arizoan color and your feet.
A little bit of pedicure for your toes doesn't hurt.
So in the end, think about that you cann't wear the Arizona with everything, while the other Birkenstocks models are much easier.
Some great examples where the Arizona really works
