The Reebok Engine A 'Metal Green' brings verdant accents to the lightweight performance basketball shoe. The upper combines a black textile base with a molded TPU overlay in a metallic emerald finish. Reebok's embroidered Vector logo adorns the tongue and heel tab. The midsole combines a shock-absorbing SuperFloat foam core with Reebok's ERS technology, made with nitrogen-infused foam for a blend of stability and energy return. Underfoot, the durable rubber outsole is designed to grip the hardwood in all directions.
