Loads of happy years in Scarpa Mantas with Vibram soles, no problem.
Bought a pair of Scarpa Cerro Torres this year to get a bit more serious. Got a bit more serious - no problem. They have Vibram soles too, I think ?
Late summer this year, got out my old Daisy Roots Sympatex lightweights for a gentle trundle up Bristly Ridge. My word, that was scary. No grip whatsoever. I think they're a much harder rubber.
I suspect it depends what you've got yourself used to.
I suspect also that "Vibram soles" can't all be the same ?
Do they not tailor the compound (ie. hardness) to the intended application, at least a little bit ?
