Yes, the insert is removable; I believe you can rip it right out. But, eventually if you ever want to wear really nice shoes, you'll pretty much have to say good bye to those orthotics. Eegad. Hopefully the orthotics will fix my feet by the time I'm done growing. I'd really like to avoid having reconstructive foot surgery (which I've been told is the only alternative to orthotics if my feet don't get better on their own). Thanks for the info on the Sperry insoles, though!
