Charmodel - Blender to Unity? Feet are twisted, how to fix?

when importing .blender file: (but Animation is fine)

when importing fbx : (Another Problem Occurs: Animation gets sloppy?)

when importing fbx ASCII: (but Animation is fine)
Same as with .blender file but whole character scaled to size of an ant.

I think it has something to do with the toebone of the rig, but i can´t figure it out. help pls

Ok so now I go it fixed after hours of research and comparison between earlier blender files.
I changed the location of the lower leg bone head after using custom shapes ,bad mistake. Changed it back now everything works fine.
