Could you please tell me the European size number? And whether they are reg/narrow or reg/wide? The top of the item description says women’s, then 11/11.5, which in Birkenstock land means 42 reg/narrow but at the bottom it says men’s 11/11.5 which is like 44 or 45 reg/wide.
I wear a 42 reg/wide in Birks so 
Amazon’s insistence on "americanizing European shoe sizes in hella annoying. Especially here where there’s no size chart and two different descriptions
Hi there. These are being obtained from Amazon inventory so we don’t have a lot of information. Here it is on Amazon. There may be more information there.

That’s all it says there. Behind the scenes, I did see 43EU.
