In reply to pasbury:
I've got a pair of Haglof Vertigo's and a pair of Boreal Flyers (ordered two pairs meaning to send one back, and never got round to it). The Haglofs are extremely comfy but are already showing significant signs of wear after 6 months, and the spongy sole means they are rubbish for edging. The Boreals have a thinner sole so not too comfortable on a long walk-in, but are much better for scrambling, with a good edge and a sticky sole. Horses for courses I guess.
