In reply to StuartCJones:
If you're not wading through too much mud on your 'approach', I think the Evolv Cruzer might be worth a look. Grippy low profile sole, which is good enough for easy routes, and they're light, come in funky colours and have a loop to karabiner them to your harness.
And when I got them they were significantly cheaper than some other, admittedly more burly, approach shoes that were more like light hiking boots.
