I happened upon this thread today..Awesome! I'm a Birkenstock girl...out of necessity. Foot problems and my podiatrist recommended them. I was not excited, but really, they are great. I've never gotten them before because I can never find them in my size...BUT, when I had to start wearing them for my issues I got onto Zappo's to order.
I wear narrow and am a size 9 1/2 to 10. Got both 40 and 41 to try and 40 fit the best. They do tend to run a half size smaller.
They are the most comfortable shoes I have ever worn, and I can stand on my feet for a long time and walk around town in them with no problem. I never have flare-ups of plantar f. or tendonitis in these.
So glad they come in cuter colors and styles now. I have skinny feet and ankles so they don't lookquite so clunky on me.
I think I've had mine about 3 years and want to get a few more. I have the Arizona in black suede, the Gizeh in brown leather and black patent leather, the Mayari in black leather, and another one in black patent that is similar to the Arizona but with thinner straps.
The Gizeh is my favorite. It stays on my feet really well. The Arizona feels like it's going to slip off my feet and makes my feet tense up a bit when walking. I think the Birko-flor's are fine. They have the cute colors and designs.
I've seen a few actresses here and there on the web wearing them (one that comes to mind is Naomi Watts), and I always think how sensible that is! (Haha)...Oh, the one I couldn't remember the name of is the Sydney.
