The Nike Free Metcon 4 combines flexibility and stability to help you get the most out of your training program. The updated "link" mesh cools and flexes as you accelerate through agility drills, while the midfoot and heel support protects you for your heaviest sets in the weight room. Blast from the past The 4 brings back the super tough yet breathable mesh of the original. The upper is adorned with Huarache -inspired webbing and a rubber-striped sidewall that wraps around your heel to prepare you for movement in all directions. Flexibility for speed Nike Free technology in the forefoot creates flexibility for agility movements and sprints. Stretching around the collar allows your foot to move naturally as you burst, cut and brake. Stability for strength The wide heel creates a solid base for lifting. A softer foam core cushions your foot, while a firmer outer layer is durable and stable. The wide inner strap distributes pressure around your midfoot for a comfortable yet locked-in feel during hard stops and quick cuts. More Benefits Rubberized logo on the tongue reminiscent of the Huarache of the early 90s. Rubber tread in high-wear areas gives you durable traction.
