In reply to ColdWill:
From a quick scan of prices: one and a half pairs of Nepal Cubes, but two pairs of Nepal Extremes if you don't mind shopping in big French sports behemoths.
Considering that I bought my Nepal extremes in 2000 and they are still in fine working condition now, two pairs would almost certainly take me past my average life expectancy, so would probably see me out - which whilst a fine recommendation for boots, is somehow deeply depressing a thought!
I hope that if Scarpa are charging 500 quid for these beauties they've put a sole on them that doesn't wear down super quick or even worse crumble off in bits!
