The silent foot steps

I know this isn't a big deal, but it's really bother me that there isn't a single foot steps sound effect in the game. Even it's just a quiet foot step, I still want to hear it in the game. It will make the environment to have more activities. Furthermore, it will be cool to hear the different foot steps sound effect from each different Champions. Example, with his insect's legs sound, with his heavy metal foot steps sound, with his horse's foot steps sound, and many more... Is it possible for Riot put some work in this area? Can I expect to hear these beautiful sound effects in the future? Please Riot, give this some thoughts.
