EDIT: Oct. 22, 2016 - I have now had these insoles for a year and a half and literally wear them every single day. I transfer them from each pair of shoes to the next. They have held up SO well, both visually and functionally. I truly believe that my feet were saved by these insoles.  As a non-car-owner living in New York City, I do a TON of walking every single day. It wasn't until recently that I realized the reason that my feet hurt so badly is because I have a high arch. Granted, I do not wear extremely high end shoes with lots of padding and support built into them. These soles have helped so much already in the first few weeks that I have been using them. I wear size 12 shoes and the mens 11-12 fit in all of my shoes perfectly. I transfer them from pair to pair to pair so that I always have them in. I wouldn't be surprised if I end up buying another set of these insoles in the near future.
