Question 1

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

Accepted Answer

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

Question 2

What's N and M ?

Accepted Answer

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.

Question 3

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

Accepted Answer

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

Question 4

Are these real birkenstocks?

Accepted Answer

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.
