In reply to Black60six:
They are not B2, and are unlikely to be B1. The edge between B1 and crampon-incompatible is a fairly ill-defined one. Grab the boot in both hands and try to bend the toe up towards the ankle. If I do that with my B2s, there is no perceptible bending, and my B1s bend about 15 degrees. If you can bend it more than about 30 degrees you're going to have a rough time putting crampons on them.
If the boot is too soft, you will find the crampons come off and/or you bend the boot into an uncomfortable shape tightening them up to keep them on. You'll also find it uncomfortable the way they bend, and it'll be difficult if not impossible to use the front points properly on steep ground. Make a habit of using a C2 articulated crampon on a soft boot, and the crampon will get knackered too.
If they are too soft (and I think they will be), you could try and hire some B2s, either from the place doing the course or a nearby outdoor store.
