I'm designing creatures on my made up planet where animals evolved exceptional hearing and I'm wondering what kind of feet they might evolve to produce the least amount of sound when walking to avoid predators. For some more context I imagined how life would evolve on a planet around a red dwarf with low luminosity. This made plant life extremely competitive to gain as much sunlight as possible with one species eventually evolving to nearly cover the entire sky with their leaves blocking out the little sunlight the animals had. Due to this animals have to mostly feed off fungi and dead leaves on a rocky environment with big tall tree like plants here and there. So prey and predator had to rely on sound to detect each other so I'm wondering.
What kind of feet would they evolve to reduce noise in a rocky/dirt environment?
