hi! I've 2 pairs of crampons: the Grivel G12 steel and the Grivel Air tech aluminium. they are perfect for my boots size 8 (Celcius cirrus lace)! I think G10 are good, and un little more light than the G12...

I have had a pair of Petzyl Vasak 12 pointers for last 2 years, great general purpose strapon so works on many boots. I was very pleased to find they fitted absolutely perfectly onto my Spark Deeluxe boots, perfect fit nice and safe no chance of slipping off, and I can operate them in flex or stiff mode if need I just left them in flex mode. The Spark Deeluxe has the Vibram sole , thats why it works so well!
