In reply to nickinscottishmountains:
It does depend a bit on where you're going to be. You can obviously approach Stanage in anything, but I've given up on wearing my cheap trainers for any approach that involves a bit of a scramble (or descent for that matter), the rubber is terrible on rock and I've had a few wobbly moments and I struggle to trust my feet now. I also tried to rig an abseil at the top of the Verdon Gorge in flip flops and went flat on my arse, right next to a 200 metre drop. Maybe I'm clumsy
, but approach shoe rubber is why I use approach shoes.
