Shoe advice, flat feet and high overpronation

I don't have a proper gait analysis, this is what I got from the Asics showroom..they told me that i have high overpronation and suggested I go with kayano bcs of this.

I tried the kayano and ran for around 3-4min on the treadmill and it felt better..but not sure how it will be in long-term.. considering it's a high ticket item or should I be looking for another set of pairs? I tried gt2000 too but they were not good feel compared to kayano32
