Unparallel Flagship LV Sizing

Anyone have any experience with the Flagship LV sizing? Currently wearing a Scarpa Instinct VS Women in 35.5 (I have a 225mm foot length). Not sure what to go for with the UP's...I live outside of the states / too far away to try them on in person and ordering multiple isn't an option.

In my experience, I had Scarpa dragos LV 39eu, and wore flagship LVs in 8.5USW (7USM). I think this site is pretty accurate for sizing, so try this: https://mountainfootwearproject.com/
