I have a set of Currex RunPro Mediums in my RC Elite 2s (mainly because the normal NB sockliner keeps slipping towards the heel). I like them better than Superfeet, but generally I try to avoid aftermarket insoles and stick to shoes that don't wreck my ankle. The inov-8 ones are just to add more cushion/bounce, not support. It's like adding a thin layer of boost, but are a little thicker than typical insoles.Have you tried the Currex Run Pro Low?
