Support, support, support! We've been fed this for years, but when you really need to fly what goes on those feet? Light, flexible, and minimum is what you look for, right. Who would run a fast x-country race in a overbuilt shoe? No one in the top twenty! So now your running on trails and you expect the overbuilt trail shoe to make the grade? When you are contouring how can a shoe built to keep you from rolling one way work on both feet? They do not! The Flyroc is built with the idea that your foot is designed for trail running and it lets the foot do the job. Light, flexible, low to the ground, protective sole and breathable upper combined to make a great trail shoe. When I first put this shoe on and hit a rugged MT Rocky Mountain trail my ideas of what makes a good trail shoe changed, and I started representing Inov-8 the next day.
