Our approach for the GT-1000™ 13 shoe was to modernize the shoe with more support and elevated cushioning. This design features a 3D GUIDANCE SYSTEM™ to help increase stability for a more balanced stride. The shoe is reimagined with PureGEL™ technology and FLYTEFOAM® cushioning in the midsole. This helps create a lightweight feel with softer landings so you can experience more comfort in each step. Style #: 1012B663.004
