Too narrow!!!!
I bought these in lime, orange, and berry. The colors are great, and the Birko-Flor is okay, thought I prefer nubuck. Alas, they do not come in regular width in these colors, only narrow. I sized up but they were still too narrow and hurt my foot. I have many pairs of regular width
Birkenstocks, and I love them. I do not agree that their narrow is an American normal width, unless you have very skinny feet. Betula makes this style (they call it Grace) in only one width, and those fit me fine.
