In reply to TomGB:
+1 for La Sportiva.
Specifically the TX4, super comfortable (avoid TX2, horrible fit), amazing grip on anything and everything, I wore them for a forest+rain+snow+ice winter in New Zealand for 5 weeks, pretty much never took them off, best shoe of its kind I've had in years.
Also, Andy Kirkpatrick had some nice things to say about them:
