Nike Free Metcon 4 combines flexibility with stability to help you get the most out of your training program. Super-tough yet breathable mesh from the original version cools and flexes as you speed through agility drills. Nike Free technology in the forefoot creates flexibility for agility moves and sprints. Stretched added around the ankle lets your foot move naturally as you burst, cut and brake. Wide internal webbing distributes pressure around your midfoot for a comfortable yet locked-in feel during sudden stops and quick cuts.
