In reply to Professor Bunsen:
I've used them for Scottish winter, summer alpine, and short winter alpine days. Scottish IV/V, WI 3/4 and easy alpine mixed. Fine for all of that, but don't quite fit my feet too well.
Struggled to get crampons to fit them as the toe box is rather narrow. I settled for Cyborg Pros with a narrow toe bail. The problem might not be so bad on larger boots, but my relatively small size 41 feet were a bit of a problem. Might be better with a basket and bending the front posts inwards, instead of a front bail? Good boots though.
