In reply to Chris Beck: Many thanks to everyone so far for the advice.
Heard reports of people grinding the sole to make the crampon heel fit better..not sure i am keen on that just yet.
Jon Griffin mentions in his write up that the , Petzl Darts fit fine without modification...maybe there the way to go?
Would been keen to hear more advice from people on Mono point crampons , they have used with there Spantiks.
Just so i can get a few options before i order some down.
I dont live in the Uk and hard to get hold of Petzl crampons to try on... hense why i am asking on Ukc.
Many Thanks
