Hello.
I've got a pair of these and I tramped around in them for a week in the wet and snow and they were absolutely fine. The will also take crampons, though not C3s, but I think something like this which is quite stiff will do the job for lots of walking and some crampon stuff, but not quite be stiff enough for any serious ice climbing.
Looking at them more serious winterboots you've been recommended, they look a bit stiff to me for what you are on about doing, but as others have said they all fit a bit different so just find some that fit your feet most importantly.
Anyway you can stick crampons on all sorts of boots, don't be afraid of the hype I say.
