Is there anyone here who has faced a similar situation like this?

Hey,
I have been dealing with feet issues for quite some time, mostly due to my flat feet and have finally decided to get custom insoles. I went to the doctor today he did a mould of my foot and ordered the orthotics.
So my podiatrist made me some custom orthotics to combat nagging plantar fasciitis and a heel spur. I am going shopping for new running shoes tomorrow.
I'm wondering what shoes I should wear? Is there anyone here who has faced a similar situation like this? Please do share your experience.
