The Nike Metcon 4 XD Patch takes on the dynamic components of cross-training with an innovative construction. Unveiled in April 2019, this 'Triple Black' edition stabilizes the foot and allows for breathability through a 3D-printed haptic shield and mesh upper. Flywire threads loop around the laces for enhanced lockdown. Customizable badges add a personal touch. The drop-in midsole and tri-star rubber outsole are stacked underfoot.
