I love my La Sportivas – got both Raptors and Wildcats, alternate depending. For shorter distances the Wildcats are better…
That said, what kind of footpaths is she running on? If they’re in reasonable condition without too many stones, rocks or mud there’s not much point in getting trail shoes. I spent at least 10 years running off-road using normal road shoes, it was only from last year when I started to hit the properly technical stuff that I decided some more specific shoes would be useful. They’re definitely more comfortable and have better grip, but a lot of the time they’re overkill.
Still, if the Boss has said she wants trail shoes go for it. I’d personally head to a shop and get some that fit properly – far more important than any anecdotal evidence I or anyone else can provide.
