How can you stop high-heeled shoes from clicking on hard floors?

Here are some suggestions:

If you go to a shoe store they have little rubber pads that are glued on to the heel of the shoe. This should stop it clicking for a while. The pads are used to keep the heels from wearing down.

There is a cheap way, duct tape.

You can walk a little on your tip toes.

My friend used to stick non sticky gum and it never clicked, or you could just put glue on the bottom let it dry and it will be a lot quieter. You will barely hear it them.
