The 4 is bringing back the super-tough yet breathable mesh from the original version. The upper gets embellished with a Huarache-inspired strap and rubber-striped sidewall that envelops your heel to brace you for movement in any direction. Nike Free technology in the forefoot creates flexibility for agility moves and sprints. Stretch around the ankle lets your foot move naturally as you burst, cut and brake. 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. Wide internal webbing distributes pressure around your midfoot for a comfortable yet locked-in feel during sudden stops and quick cuts. Rubberized logo at the tongue nods to the Huarache of the early '90s. Rubber tread in high-wear areas gives you durable traction.
