I work in school buildings, so they are generally big and echoey (while classes are in session) and made of slippery tile. I don't like my shoes to announce to the building that I'm coming, and I especially don't want my footsteps to disrupt a classroom. Slipping is also a bad thing (I once had one heel slip and ended up doing the splits!).

So does anyone have any suggestion for shoe silencers? Perhaps adhesive additions to the sole? It is most important for heels, but some shoes are clicky all over, so the front clicks, too. I've seen heel savers, but those aren't specifically designed to quiet shoes, but rather to keep them from wearing as fast, so they are often hard and loud, too.

I know other people must have this issue, but either I don't know the correct search terms, or no one has solved the problem (which I cannot believe is the case). Any suggestions? I have several fantastic pairs of shoes that I rarely wear due to this issue.
