Heidi Klum and Tim Gunn pit the Project Runway contestants against each in a mad dash to the finish line at the New Balance Track & Field Center.  For this week’s challenge, the contestants will create a look for the Heidi Klum for New Balance collection, which launched Fall 2010 exclusively on Amazon.com.

Judges Heidi, Michael Kors, Nina Garcia and guest judge Erin Wasson, will make another designer’s dream of designing for the masses come true tonight.  The winning design from tonight’s episode will be available for pre-order beginning tomorrow, August 26, on Amazon.com.  Digging the kicks worn by the contestants on the show? There are now available at www.amazon.com/HKNB.  Carry on!
