In reply to Keen2go:
Sorry if this isn't in the spirit of the inquiry, but...
... doesn't need to be very warm, it's not some 6000m/planned overnight/subarctic epic
... doesn't need to be very stiff, if you're front pointing things aren't as they should be, just something that will take a boot crampon
... doesn't need to be very light, this isn't an athletic achievement that depends on shaving grammes off (if you're looking at it that way, go and get fitter and practice descending steep loose ground fast)
So choose a boot that fits well and suits your activities and aspirations and budget, whatever they may be. I'm just reflecting on whether I could have used my 1990-style B1 Mantas, and thinking yes I could, and it wouldn't have been irresponsible, it would have been fine, but in fact I owned and used something stiffer and which, had there been an accident, wouldn't have looked bad in the accident report.
Assuming from context the Hornli ridge. Best of luck, go well.
