The upper of the Nike React Element 55 Dynamic Yellow is primarily constructed from a lightweight and breathable mesh material. The Dynamic Yellow color dominates the upper. This bold yellow hue extends from the toebox to the heel, covering the entire upper. The design includes synthetic overlays in key areas, such as the eyestays and heel counter. The Swoosh branding is typically rendered in a contrasting color, providing a sharp visual contrast against the yellow backdrop. The outsole features a unique pattern of rubber pods, strategically placed to provide traction and grip on various surfaces. This outsole design enhances both the shoe's performance and its visual appeal.
