Fans of high heels and shoe inserts (e.g. Foot Petals, Apara, Insolia), here's another option for you. Like the ones by Apara, Bama "Smiling Feet" pads are made of transparent silicone. Bama, however, in their infinite wisdom, has made them re-usable. Simply wash them to make them stick again. There are 6 different kinds to choose from, depending on where you need your padding. I find the Gel Cushions, for the balls of your feet, to be the most useful because they also prevent your feet from sliding forward as you walk, and Bama's version has little raised bumps for additional friction. I also like the Gel Mini Cushions, which you can stick on the sides of your shoes to prevent blisters.
