I bought this shoe, which is more like a low fitting boot, for its width fitting.
I have used NB before, and there can be a problem with the wider fittings having a looser heel fit.
I therefore settled on the slightly less wide fitting (ie 2E).
The 978s have an advantage in that they have a C-Cap midsole, and therefore seem more comfortable over distance.
That said, I tried them for four miles, and noted that one was more comfortable than the other (I have feet different by half a size).
I proceeded to wear them for increasing distances, culminating in the 2011 Lakes 10 Peak Challenge.
I did not complete this event, mainly due to trying to descend Great Gable on my face.
Nevertheless, I did complete 9 peaks, and well over 30 miles, with no problems for my feet - or perhaps it just felt that they were less painful than my face.
The 978s performed well on Helvellyn, the sucking peat of The Bog, the usual Lakes loose scree, the abrasive slabs on Broad Crag and on to the varying terrain on Pillar. Although it was a dry day. I have worn them through wet weather with good water resistance from the Nubuck leasther, helped by Nikwax after the first few days.
Unlike other Goretex lined boots / shoes, they don't seem to make my feet feel hot.
They have now replaced my third pair of Berghaus Explorers, while I save my Scarpas for more robust trekking.
The soles are not as aggressive as the Explorers, but are almost as grippy in the dry and better in the wet.
At the price, they represent good value for money.
