Initially produced in '89, Reebok's ERS 2000 sneaker is defined by a system of tubes that bring bouncy return to the running experience. This iteration holds a grey neoprene upper teaming green synthetic suede, 'Berry' premium eyelets and reflective heel piping. Bright logo stripes pop on the sides and the brand's signature is embroidered throughout. A responsive tricolor midsole and rubber outsole offer impact protection and stability.
