Thanks for the feedback, I am highly appreciative.
I tried on the Bauer One20's yesterday and had plenty of room up the front (width wise and perhaps too much) the rear pinched a little and were no where near as comfortable on my feet as the Eastons were. So I think I'll be going (well asking) for the Eastons, having them on for 20 minutes and having no pain or feeling of relief when taking them off was a good sign.
My wife has relatively flat feet as well, she tried on Reeboks, Bauers, Eastons and also Grafs and out of all four she only liked the Grafs. The Reeboks (and I'll agree) are uncomfortable, the Eastons for her had too high an arch support, the Bauers were ok, but she loved the Grafs, they fit well and she had them on for a good 30 minutes standing and walking around in the shop.
Being in Australia we have a) inflated prices and b) limited range available at the dedicated skate shops which is a shame, but thumbs up to the sales guy (an avid Hockey Player from Canada) who spent over an hour with us going through options.
Also agreed. Sounds like you took the right time to asses what you need. All and all, everyone has a different feel, and if it's right, it's right. Everything can fit perfectly after they bake them (or put them in the heater and mold the gels to your feet). I still say Bauer
