The boot enchant and Muffled Movement perk each gives you 0,5 pts muffle, but I'm not sure how they stack. Together, they'll either give 0,75 or 1, but I'm guessing the latter. Having "1 muffle" or weightless armor (through perk or Steed stone) will make you completely silent.
The Silence perk may give you 1 muffle from the way it's described on the wiki, but I haven't looked into that myself.
A high sneak value can indeed "tick over" and make you worse at sneaking, so until that's fixed I would go with a Muffle enchant or resistances if you're already silent enough.
