Inov-8's trail running shoes have been in my trail running quiver since 2006. I particularly like them for trail and mountain racing due to their low to the ground light, nimble feel ( the original minimalist trail running shoes) and the wide range of models for different types of terrain and speeds.
I can't wait to try their new range of road shoes out this spring. Much as with their trail shoes the road models focus on a progression in weight and function. The 3 Road X models bring runners closer to near zero drop/barefoot from model to model by using a three step progression from 9mm, to 6mm to a 3mm heel to toe drop . I think I will start with the 233 (233 grams) which comes in at 8.3 oz and has a 6mm heel toe drop, quite similar to my Saucony Kinvara.
