In reply to mrbird:
Arcteryx (yes i know ...silly expensive) norvan vt. Ive had a pair for a couple of months now and literally been out every day in them. Most versatile shoe ive had...
Ive ran 18 miles over a mix of munros and tarmac carrying a daysack with no issues, scrambled 4th class stuff with ease, done a few short sharp hill runs and been out walking in them.
Way grippier than speedcross and seem to be holding up well..ive even tourqued my feet in a few cracks and the shoes havent complained.
Not super studded sole so gloopy mud isnt great but flat lugs are wearing really slowly on a lot of shoe eating scrambles.
Two months in x talons on the stuff ive been on has left the studs totally destroyed...the norvans are almost like new.not too heavy either for a shoe with approach levels of scrambling in it.
I agree speedcross are great for comfort but rubbish for grip on any damp or wet rock...by rubbish i mean lethal!
Best shoes for running combined with scrambling for me are walsh PB elites....unbelievable grip once you wear in the studs a little...sadly they wear out super fast and fall to bits.
Hope this helps.
