Okay, so both pairs arrived. I am usually a 35.5 in the Oran sandals. The black Chypre 35.5 just fit. When I walk around my front toe hits the rim a bit but when standing my foot is fully in the area it should be. The white pair in 36 gives me a smidge more in length and are probably the "right" size for me. BUT, I think I will get more wear out of the black and will probably keep them. I just did another walk around and the rim is not bother me at all... There is hope for you!
Let us know what you decide once your pair arrives.
