I've been running for about a year now and I've known I am a moderate overpronator. I've always used stablilty style running shoes, Asics 2120 and currently run in Brooks Adrenaline 9.
I was wondering how it would work if I switched the standard insoles with performance insoles like the New Balance Multi Sport Cushioning insole.

Would switching insoles effect the way the Adrenaline controles the pronation of my foot? Would it be better to switch the insoles or to leave the original ones since the performance insoles seem to be for medium/high arches, where I have a very low arch?
