I'll comment on the Salomon option...
I haven't tried the model you've selected, but I do have a pair of almost identical-looking Salomon Sanford GTX shoes.
The shoes are comfortable, very lightweight, quite grippy and the waterproofing has lasted a relatively long time. They're close to being like a trail running shoe and are great for moving quickly on difficult surfaces. I like these shoes so much that I bought another pair for when these wear out (not long now!).
The main difference between the Salomon Outline and Sanford is the tread. The Outline has a trail running pattern, whereas the Sanford has more a typical walking pattern. I suspect the Outlines wouldn't last long on tarmac or concrete but would be excellent for off-road use.
