It is called Championship, because it is different from the others.  Upgraded boot from the Champion AG boot.
less weight @ 233 gr than the Champion.  The upper is made of lighter and breathable microfibre, which does not absorb water while retaining its original lightness. Traction-resistant lining made of nylon. With ONE PIECE technology, using a single, seamless piece, assisting its adjustment to the foot and preventing weight increase. With WATER RESISTANT technology (which prevents water absorption and retains its original lightness) and M COUNTER technology: a buttress at the heel providing better protection and greater comfort thanks to its ergonomic shape.  Semi-rigid PVC insole to firmly retain the structure of the sole studs throughout the shoe’s useful life.
Pre-shaped EVA lining insole that adjusts to the shape of the foot and PU sole, with a structure that prevents torsion in the central part.
