I had several different Scarpas before and I liked all of them a lot. So I ordered Rockette 34, 34.5, 35 (my previous shoes were 34.5, my street size is 36, I have narrow foot)
Unfortunately I couldn't even put Rockette (35 size) on my foot - they are that small! I compared them with La Sportiva Miura VS, size 35 too - Rockette are about 2cm less.
I ended with another shoes, hoping that next time I get more luck with sizing.
I rated these shoues basing on visual examination. (I also know that men's version of these shoes - Scarpa Booster works great).
