Nike Dunk High PremiumWith this Dunk High Premium, Nike decided to break out a nice mix of colors and materials. The upper features a combination of heavy canvas, smooth leather, premium leather and premium perforated leather on the toe box. Sometimes a Cool Grey and Natural Grey color scheme has the tendency to bland, and Nike knows this. So, they added a lil' funk to this Dunk with a Berry swoosh. And, it all comes together just right.
