In reply to Got a job rob:
There's a hell of a lot of difference in the width of those three boots. Are you absolutely sure that they all fitted?
Did you try on the boots without the liners? Which gave you the most appropriate heel gap when shell fitting? (I would say aim for no more than a 20mm heel gap).
Quadrant: Good boot if they fit, but very wide.
Factor: Narrower. Somewhat heavy. Liners are lasted short in the full sizes, so difficult to get a good fit in full sizes, half sizes are better in this respect. So whether the are good boot may depend on whether you need the full or half size.
Maestrale: Light. Good if they fit, be careful with the tongue hinges as some people break them.
Maestrale RS: Might be better than the mango Maestrales if you prefer stiff boots, what have you skied in before? Did the Glenmore Lodge boots feel stiff enough? The RSs will be much stiffer than the Glenmore Lodge boots.
