In reply to PPP:
I depends on the construction of the midsole and dobs. You will always clatter about on road and wear the dobs down quickly.
I've done long days in the original Inov8 Irocs and had no issue. These had a fair bit of cushioning and some design to help soften the impact of the dobs on your feet
I also used a pair of VJ Bold (more aggressive orienteering shoe) in the Trigger race in 2017, when there had been now the day before the race and a decent thaw overnight, but still quite a bit of ice. I seem to remember the bottoms of my feet aching a lot after that, but I was glad I chose them for the grp on the icy bits. The western edge of Kinder was ankle deep in wet slush which softened the feet up nicely in the4th hour of a long hard race - my feet were very tender, on the base but also elsewhere from the lack of softness of the upper. The aching was likely magnified by the stretches of flagged path, harder trail and road at the end of the race. Still one of my top days out mind.
I wouldn't do the Cheviot Goat in aggressive dobs like the Bold, but the Sarva looks a bit more cushioned. However, the uppers look like they don't have much on them so the rest of your feet may suffer if you wear them for that long.
