Superfeet
I usually advise patients to start with the Green color.
Try it on to make sure it is comfortable.
Feeling different is ok.
If the insole hurts your arch, try a different color.
Blue or Pink/Berry would be the next step.
There is also a 3/4 length EasyFit device that is great for dress shoes or flats.
