The Nike Free Metcon 4 Black is an all-black workout shoe designed with stability and flexibility in mind. The upper is crafted from a durable yet breathable mesh with a loose weave that helps the foot stay cool. Nike Free Technology in the forefoot promotes flexibility and range of movement during exercises, such as burpees or planks, while the wide heel provides a solid, supportive base. Tube-like laces in black wind through the reinforced eyelets and provide a secure closure. Although they’re hard to see because they come in tonal black, branding details grace the outer side panel near the toe, the midsole, and the tongue. The soft foam core provides responsive, lightweight cushioning underfoot, while the traction design and pods provide grip. The Nike Free Metcon 4 Black was released on April 1, 2021, and sold for $120.
