Arch support real or gimic?

Fitamdshiit

So I am a new runner. I've only been at it for about a week. Doing a couch to 5k program. I've been running in my vans. Which have no arch support or any real support going on. Haven't had any pain or discomort at all (minus the ache of worked muscles). Ive been running up and down hills outside. Still, i figured i better get some running shoes. So today i went to a running store. The guy was so friendly. He measured my foot and looked at my arches. He said i have really high arches. Then looked at them standing up and he said they collapse 50% under my weight which is rare. So he recommended an arch support insert with my shoe. So i bought it no questions asked because i want to succeed. When i got home though i started thinking about it and I've never had any pains in my feet or during my runs. Will arch support weaken my arches? Are they necessary if i have no pain? Thoughts?

I have a few kinds on tendonitis and fascitis in my foot. (Seriously I won the "i'm *kitten*" lotto on my foot problems) I wear special inserts and I definitely feel it if I don't wear them or if I wear sandals with no arch support.

Oh yeah I believe that if you are having issues they are definitely not a gimic but in my case I wasnt so sure.
