the sizes of the problem

I love the model.
footwear of 37, I pass first order demonstrates to me that it is too large.
Back of the package.
Second in command 36 that is clearly too large.
With other brands this problem never happens, I remain puzzled ...
return of the parcel once again.
Conditions occasions at Amazon and repayment time are perfect.
But I have still no Birk, and will therefore try a fitting in stores.
The time to do this and then find a promo model that I like, maybe we will already be in winter ...
I'm very disappointed, but the service is Amazon him satisfactory.
