The adidas UltraBoost "Non-Dyed White" gives an energetic ride for both marathon runners and weekend warriors. Built with plenty of performance enhancements, the adidas runner doesn’t sacrifice style either. The shoe is equipped with a white upper that's sprinkled with black flecks in the material. The rest of the details are completely white. A Stretchweb rubber outsole flexes with each step for adaptive comfort, with a Torsion System midsole for stability. The Continental rubber outsole provides extraordinary grip for added stability and secure push-off.
