I just wanted to share my favorite heel pads. These little guys are magic. Generous cushion, nice soft suede, and although they don't budge, they don't hurt the shoe if you want to remove them. I use them to keep my feet from sliding out as well as to prevent blisters from stiffer shoes. Only $2.35 on Amazon, and free shipping if you have Prime. I don't know what shipping is if you don't have Prime, but I bet they'd be a good thing to keep in your cart in case you ever need a filler item to qualify for free shipping.

Unfortunately, they're no longer in stock per amazon. I'd sure like to find something like this, though.
