There is no design or tech involved, but simply a task in which the right colorway is chosen. Here’s a look at an unreleased pair of the Nike SB Dunk Mid; right off that bat you can easily determine this particular pair was recently scrapped due to the strapless construction, but if you need further confirmation, the production dates on the inside tag reads late 2009. The color combination features a simple mix of navy blue, yellow, and red with multiple materials, like suede, leather, and canvas.
