Bought and tried them out today. Fit is good, others Inov8 shoes (Talon, Oroc) are too narrow for my feet so I went with the Roclite (I wanted the 6mm differential, but 9 is also good for the beginning).
Looking forward to both run and hike in them and I also want to use them for my expected but not yet completely planned winter trip.
The weight for size 12 is 699 grams, which is much better than my 2 years old Mizuno Wave Ascend size 12 (750 grams excl. insoles).
All I can say after some first trail and off trail runs is that their traction is very good and I like them.
