I've got a couple of pairs of the low version of these (Goretex and non Goretex) and really rate them. A more supportive running shoe (or lightweight walking shoe!) I find them excellent for general mountain walking and easy scrambling.
They don't have a climbing zone though so depending on difficulty of the scrambling/confidence you may want to consider something more specifically approach orientated. On the lightweight side I guess the La Sportivia TX4 might fit the bill, I use the TX5 which I think is a great all rounder but is a bit more robust and not particularly lightweight.
Obviously as others have said fit matters a lot as well, I generally get on with the narrowish fit of most Sportiva shoes.
