I had a pair of MIzuno Ascend 1 (the '2' is very different) They were fine, but not overly grippy. It is essentially a road shoe with a more aggressive sole. Ok for footpaths and wet grass, but for 'proper' fell running you'd want something else.
Depends on what sort of off-road/trail running you plan on doing as to what you should get. Also dont know if ascend are supportive in the way the Inspire is.
Other options:
Saucony Omni trail
Salomon XA Pro/Comp
Asics Trabucco
all the above have medial support and are ok for some road as well. The salomons are probably the most 'off roady'.
