Salomons, specifically that model of shoe you're referring to, are built on traditional running shoe lasts (10-12mm drop) and a 20-24mm stack height (outsole+midsole+insole). Not until recently has Salomon started tweaking some of their shoe models, for the most part all of their shoe models are all very similar structurally, save for a few upper overlay changes and outsole designs (mixed conditions, trail, road, etc.). If you're looking outside of Salomon, I think you will find that Montrail makes a shoe equivalent to the popular Salomon XA Comp 3. The Montrail Masochist is very similar (heel/toe drop, outsole, mild stability) and a very capable "all around" trail shoe for hiking and backpacking on moderate trails. Years ago when the shoe came out I used them for trail running and backpacking. I felt they were good for established trails and did fairly well off trail, but the lugs weren't up for really loose trail conditions.
Montrail Badrocks are another shoe that is similar to the Salomon XA Comp 3 runners. If you want a shoe that's pretty much spot on in comparison to your aging Salomon XA Comp 3's, go with the Salomon XA Pro 3D ultra- this would be the best equivalent shoe. Just be prepared for sticker shock. Salomon is very expensive for some reason.
Personally, Brooks Pure Grits have worked very well for my running. On my fifth pair at this point and will soon pick up the Pure Grit 2. However, this is purely for trail running, no hiking or backpacks whatsoever. I wouldn't take them backpacking.
