Nike pays homage to the first American ascent to K2's – arguably the world’s most dangerous mountain – summit with this vibrant take on the Waffle Trainer. Styled in a bright yellow hue, the uppers are crafted from mesh, then overlayed with hits of shaggy suede for a more premium look. A bright blue Swoosh decorates the side walls for a signature touch, meanwhile, a mountain graphic at the tongue drives home the commemorative look.
