Dear Sarah, The "N" & "M" refer to width, N for Narrow, M for Medium. Birkenstock also uses "R" for Regular which is also Medium. The "EURO-METRC" sizing codes can be confusing, many times they will overlap them with US sizing, which can be even more confusing! I hope this helps.

Q: What's the difference between birkibuc, birkoflor, nubuck & plain ol birkenstock shoes? i am so confused!

birkibuc is faux sued, birkoflor is faux leather, nubuck is suede or brushed leather, and plain old birkenstock are made with leather.

Q: What does the M and the R stand for in the sizes? For example, what does 40 R mean?

Birkenstock usually come in two widths. Regular and narrow. Some retailers will say M, medium instead of regular but they are the same thing.

Q: Are these real birkenstocks?

To be perfectly honest with you, I won't know the difference. I wear both and the comfort levels are the same. Whether Betula's or Birkenstocks, I believe you will love them both. I just compared boxes of the Birkenstocks and Betula's in my closet. The information is the same on both. The insole:leather, foot bed:natural cork, upper, Birko-flor, sole:EVA. The same material is used on both and you wouldn't know the difference. I have worn both over 40 years and the comfort is identical. I purchased a black pair, of Mayari, from Zappos and paid over $100. They don't feel any different than the $44 Betula's I purchased from Amazon. They both feel great and who can beat the price at Amazon? Hope this helps.
