The design of FG+AG combines the advantages of FG and AG outsole, which is more obvious from the front heel nail. First of all, spikes are no longer triangles, but angular and irregular quadrangles. There are six thick spikes on both sides of the forefoot, and a raised "keel" extends from the forefoot to the hind paw. And all the "bone spurs" are AG nails. FG spikes provide the main support and grip; AG studs increase the density and contact surface of studs, and also reduce the burden on knees. This is an ingenious design with multiple goals.
