As the 2014 Winter Olympics in Sochi, Russia, draws ever closer, Nike has unveiled the Nike Flyknit Trainer Chukka FSB as the shoe that Team USA athletes will wear on the medal stand. This winterized version of the chukka silhouette features synthetic wool strands blended into the one-piece Flyknit upper for added lightweight warmth, while reflective laces and overlays deliver enhanced visibility in low light. Additionally, a speckled Free-inspired sole provides a pop of color. USA branding on the tongue and sockliner finishes the look. Fans watching from home will have the opportunity to purchase the kicks when they hit store shelves in early February.
