I'm on my 4th pair of Asics Gel Kayano's. I'm thinking of switching brands on my next pair but don't know what to.

I have accessory navicular syndrome that causes extreme pronation and just had custom orthotics built. The man that made them told me that it's good for your feet to wear different running shoes and switch back and forth on different days. Don't know if that's true or not. I also read that if you have orthotics, you shouldn't wear them in stability shoes because you have double-dosed the stability. I get confused and at around $100 a pair, I just don't want to make a mistake.
