Have you tried buying Arizona Taupe Suede?
No, I haven't owned Birkenstocks for quite a while.  Do you like the Arizona style?
quite a bit. Have you read about our materials?
I know there is a leather kind and a birko material.  I am unsure what I get since it rains a bit where I live.
There is Mayari Limited Edition Sandal available right now.
I am a size 8 but sometimes an 8.5.  Should I get the 38 or 39?  I don't want my feet to slide in them
You can check how to measure your foot length 
What about the width of my foot?
just add 31 for women's size and 33 for mens size
Okay, nice.  I will have to measure my foot and figure out which one works.
