The problem could be situational also. Have you begun a new activity to which your feet are not accustomed? Are you standing ALOT more at work? Have you recently taken up hiking or running? It may simply be that your feet need time to adjust to the new situation. I don't have enough info - just suggesting.

Also, it may be the footwear that you need to change and not the insoles.
