Get some Sugru. The instructables store sells Sugru. I got it for 50% off. It is pretty expensive. I picked black. Whola! The finished product. I think they look pretty good. Good enough for me to wear on a night out. Well, if you look closely the two heels are not as similar as they could be. So next time I would spend more time making them look the same. OK, not really. But I am ready for an invitation now. Hope you enjoyed this instructable. And maybe it will let an instructable sister get more m.

I pulled off a quarter sized or slightly larger piece and rolled it into a ball.

I pressed the ball to the bottom of the heel and rubbed it up the sides so it would stick to the sides of the heel.

I left most of the material on the bottom of the heel and shaped it by setting the shoe upright and gently pushing it down on the table so it flattened the bottom.

I shaped the sides of the Sugru up the shoes again and repeated the flattening of the bottom.

I repeated the process for the other shoe.

I did another round of shaping until the heels on the two shoes looked about the same.

I put the shoes heels up on a bookshelf to harden overnight.

Sorry forgot to take pictures of the steps and I am too cheap to open another packet of Sugru until I have something to fix. But this is so easy that I don’t think you really need pictures. Besides you are just trying to cover the bottom of the heels and make them look like you want them to you are the expert!
