I guess the answer depends on exactly what you want to do with it and when, but for me - from spring through to autumn - those sorts of deeply lugged shoes are largely unnecessary (and wear out quite quickly). You still need shoes with a good depth of tread, but I think it's a myth that you need that much year-round.
Whilst there's undoubtedly rough terrain within the Peak District (bogs, heather, gritstone), there's also a lot of well worn footpaths, tracks and trails which benefit from something with a bit more cushioning and support. I'd certainly opt for an all-rounder over such a specialist shoe for 99% of my running - much of which is on pretty rough terrain.
