Sole Patches are American-made removable adhesive pads to alleviate shoe discomfort. They come in package of 6 which will last you a long while. They are a nice, discreet nude color that blends in well with the linings of most shoes. Each has a distinct flower-like shape that helps absorb impact with each step and help enhance comfort.
Each pad has a very strong "medical-grade" adhesive that keeps it in place on the shoe. I have used other products like these in the past and my biggest gripe is that they tend to move around in the shoe after applied. That actually causes me even more discomfort than wearing my shoes without them, because the root of the pain and soreness is usually the foot sliding forward. However, Soul Patches really do stay put!
One thing that makes Sole Patches relatively unique is that they are not just intended to be applied to the ball or heel of your sole. They can actually be directly applied to the skin on the bottom of your feet! They are moisture-repelling, odor-repelling, antimicrobial, and shock-absorbing. They are designed to stay on your foot for up to 24 hours of wear, which allows you to wear multiple pairs of shoes with the pads during that period.
I found the pads I used in my high heels for New Years Eve to be pretty effective. I would say the ball of my foot usually hurts a bit in these shoes after about 3 hours of wear, but one pad in each made them comfortable for about 5-6 hours. I still have to test them out with double-padding - applying a pair of pads directly to the bottom of my feet too. I think that would do the trick for a whole day of wear!
