Nike Free Metcon 4 Training Shoe Black/Iron Grey/Volt/Black 8.5

FREE FLEXIBILITY WITH METCON MUSCLE. The Nike Free Metcon 4 training shoe combines flexibility with stability to help you get the most out of your training program. Updated chain-link mesh cools and flexes as you speed through agility drills while support at the midfoot and heel braces you for your heaviest sets in the weight room. Blast From the Past. 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.
