I always thought that the lack of unique beast-race footwear in Morrowind, and the reversion to human feet in Oblivion were just time-saving decisions made because the
realistic solution (unique footwear meshes for the beast races) would take too long to implement.
Beast races should look like beasts, and surely the armorsmiths of each have had
plenty of time to divine solutions to digitigrade foot armour. Hopefully some dev time is allocated to this
