- Brand: Nike - Model Name: NIKE Dragonfly 2 Prototype - Color: Blueprint - Size: 26.0cm Thank you for viewing. I am selling these because I personally preferred the first generation. I ran one 800m race and a short sprint in these. The included pins were only used for 200m. The included pins, pin wrench, and shoe bag are also included. This color is currently sold out, so why not consider purchasing them?
