Men sizing:  we recommend a sizing similar to street shoe size for performance fit.  Go up 0.5 or 1 US for a comfy fit.  
For example, if you foot length is 26cm, your street shoe size is 9 or 9.5 US.  Your performance fit in the Drone 2 LV is 9.5 US.  For a comfortable fit you should take 10 US.  
The ''LV'' version is very narrow, potentially the narrowest LV on the market after the Drone Cs LV.  If you have narrow feet/heel and are struggling to find shoes that fit well, the Drone series ''LV'' might be for you.
If you are used to the previous Drone version, keep the same sizing in the Drone 2.
