I also have Alpina Diablo 2.0 and recently bought semi-automatic crampons. I took the shoes to the store, where we tried fitting three different ones. Camp, Petzl and Grivel. The first two brands don't fit well at all, because the shoe is quite wide. Grivel G12 went on without problems, just had to extend them almost to the end (shoe size 45). I decided for those, and the price was reduced too. Haven't used them in practice yet. Hope soon
