Nude in winter

Hi ladies again. I have another question and I hope you guys can help me.
I am thinking on buying the You You 85. Does anyone know how is the sizing for this model?
I am usually size 36 in non CL shoes, I got the Simple Pumps 70 size 37 as 36 was too small and i could not find 36.5. They are slightly big but with gel insoles its fine.
Now I just dont know what to do with the you you's. Please help.

I don't own a pair of YouYous, but I have tried them and own 2 pairs of Simple pumps. I find that my true CL size works for both styles. Hope this info helps.
