I'm looking for a pair of aluminium lightweight crampons, my dilemma is what model with what bindings to choose.
My first thought would be a fully step in binding as the primary use will be for using with my ski boots when ski-touring. I would however really like to be able to put the crampons (admittedly fairly haphazardly) onto my trainers (5.10 guides) for snow or benign glacial approaches to summer rock routes. Finally, and somewhere it between, is it would be nice if they also fitted my summer alpine boots - Sportiva Trango Evos. Is there a crampon out there that could do all this well, perhaps with the purchase of a few extra or different bails etc?
Also, any advice and comments on the compatibility and use of crampons with trainers would be great, anybody succeeded in using crampons with a heel lever on trainers with any degree of success?
