Neutral Pronation shoe: Montrail Vitesse vs Hardrock

[rms]

Hello, I've been wearing a NB 857 (targeted toward moderate to severe
overpronator) with good comfort, and have just ordered the Montrail Hardrock
(I like trailrunning), which also mentions pronation support.

I am interested though in the Montrail Vitesse, which is a 'neutral
pronation' shoe. Could a simple archsupport insert make this shoe usable
for me, or is this a bad idea? Any comments welcome.
