Question:

I bought these pads a month ago and they are now peeling up in my shoes.  Is there a warranty on them?

Answer:

If you are a very active person, running, long walks, sports, etc.  the adhesive backing will wear down quicker with continued pressure on the forefoot.  If they are still firm enough to use you could try applying some shoe glue to keep them in place until you need to purchase your next pair.
