It just occurred to me that used sneakers in lots of snow with multiple stream crossings back in 2002. (The days were warm, however. But, cold nights)
Worked like a champ.
If Nike sneakers worked well in the High Sierra, they can probably work in the Appalachians.
The only time I wear boots is for skiing or trail work. If there is too little snow for skis, then I am wearing trail runners.
