In reply to CrankCrimp: if you're only going to wear them for approach and easy climbing
(and not as your general shoe)
I cant recommend the 5.10 insight enough.
the best sole for wet grass and rock I've ever tried, comfy on long walk ins, and fit my wide feet.
the issue with 5:10s is that they WILL fall apart quicker than other shoes, the rubber is much softer, and wears down very quickly if used all the time.
but it is a performance shoe, designed for approach. if thats how you use it, you'll get a good few years out of it.
my main tip would be to avoid the "dotty sole" style shoes like the guide tennie etc. -in the UK you're mainly on wet grass and mud on an approach, so choose your shoe accordingly.
also, consider if you actually need an approach shoe, you might be better off with xc running shoes, or general trainers.
