In reply to mmmhumous:
I'd get newmatic crampons. Not all crampons fit all boots well.
When you fit crampons they should stay on the boot when the boot is lifted without doing up the straps or rear clip.
The sole of the boot should have good contact from the back to the front points (apart from the joining bar).
The downward points should cover the sole of the boot well, they should not overhang the edges or be all based too much to one side or the other.
I'd avoid buying crampons that need an asymmetric bar to get them to fit your boot, this is just a poor bodge IMO and leaves the front points pigeon toed (pointing in the way too far), buy crampons that fit your boot properly in the first place.
G12s are very nice if they fit your boot. The only gripe I have is the front point protrusion could be a bit longer (maybe just under a cm or so), but this does make them slightly better for walking in ( and also mixed climbing)
