The Edge 10.5 is a good all mountain boot, but not for people with low volume feet (you'll struggle to touch the sides) and thin calves.
If you like features, this boot has got lots. Two positions flex adjuster, sweat saving Double Power buckles and a moveable instep adaptor (like Salomon's 3D clip). The flex of the boot is a bit sponge-ey but unless your very heavy this will not pose a problem.
Although this boot has a heat fit liner I don't think it's as good as Salomon’s. Last winters model had a small problem with water seepage but this looks to have been sorted for this winter.
All the features in the world can not make the boot fit. Have a good walk around the shop wearing them and perhaps try some others at the same time. And don't forget the custom footbed!
