V4's foot is arched for high heels, V3's is not. I have been able to get some decent V4 boot to M3 conversions with Wardrobe Wizard 2. For example, I converted Florentine Hunt boots to M3 with WW2. There is a tutorial at PhilC's that explains the different style of shoe conversion you can try. For Florentine Hunt, I choose "High Heels". That will keep the high heel shape to the boot. I just had to turn off M3's foot and toe in the Hierarchy folder (if you don't the feet and toe will poke out of the boot). Using this method, you can convert shoes from V4 to V3, but if it is a strappy sandal with the foot and toe showing, you need to use the other method of WW2 shoe conversion. Make sense? bB
