The Nike Metcon 4 XD Patch is a tech-driven sneaker developed for cross-training. Issued in April 2019, this monochromatic 'Dark Stucco' variant works a stabilizing haptic shield combined with a mesh counter for breathability on the upper. Integrated Flywire cables anchor the laces for a locked-down fit and feel. Removable patches customize the profile. The rubber outsole's tri-star pattern wraps the sidewall of the cushioned midsole, helping to enhance durability.
