In reply to radddogg:
You missed a good gag opportunity with the headline - obviously it should have been "Decent descent shoes".
For years I used some Innov8s, they are pretty knackered now, but last year I got some Adidas Kanadia trail shoes (in very fetching orange). They were cheap off some internet site and only cost about 30 quid. But most important, like the Innov8s, is they have heel tabs you can fit a krab through meaning they are fine to carry on your harness and they are light, but they are also fine to walk in for a few kms unless its absolutely wet and muddy. Things like the Evolv Cruzers are probably great for dry, non grassy walk-ins but I wonder if you they are a bit slippy or soggy for your standard UK moorland walk in?
Sportiva do those ones specially designed to be looped together and hung from your harness. They look great but aren't cheap to say the least!
