Inspired to the technical characteristics of two popular Michelin tires, it’s realized with two different compounds (Dual Compound), softer in the inner part for better grip, a harder and more resistant one on the outside for improved shielding from abrasions and wear, X-Fire features aggressive sculptures in the toes area for optimal traction even on loose terrain, while those in the heel area help to improve grip and stability when the foot hits the ground. The cleat area – with extended adjustment range for greater versatility – was conceived with a special design for faster clipping and better grip. In addition, Northwave X-Crossbow construction extends the heel area’s elasticity, improving the shoe’s shock absorption.
