Seeking to create a more innovative and comfortable insole using state-of-the-art materials, Gordon and his partner, Jeff Milliman of Greenville Running Company, went to work. The fiberglass material, which is less stiff than carbon, proved to provide greater comfort and gave the energy return they were looking for. THE SOLUTION After extensive research, Gordon found the material that met his requirements: Avient’s Polystrand™ unidirectional thermoplastic tape.
