Two-time 'Fittest Man on Earth' champion, Mat Fraser was never satisfied with second best. Earning the title two years in a row, Fraser wore Nike's Metcon 4, helping him move from silver to gold. The Metcon 4 XD 'Light Camo' fuses performance components from its previous iterations with updated 3-D technology for traction. The stronger TPU heel counter provides stability for lateral movements while a Flywire cable lacing system ensures a more secure fit for burpees, box jumps or a place on the CrossFit podium.
