Restylane for the balls of your feet

Using Restylane for the balls of the feet will work depending on what is causing your foot pain to begin with. You will likely need a good amount of product to make any difference (more than 1 syringe per foot) and the result will be for a few months. This is considered an "off-label" use and if you decide to go forward, I would recommend having it done by a board-certified dermatologist or plastic surgeon.  Again, success depends on what part of the foot you are looking to use this filler for and the underlying cause of your pain.
