**REMOVABLE INSOLES** The fit of the GT-2000™ 9 shoe has been redesigned with a one-piece mesh construction to create an improved fit. This new upper material has also been reinforced in key areas for added support as the foot rolls through the gait cycle. The shoe's upper is also made with recycled materials, while the sockliner is produced with a solution dyeing process that reduces carbon emissions and water usage. Lastly, a combination of FLYTEFOAM® technology and GEL® technology cushioning are positioned in the midsole to help promote lightweight comfort and reduce the overall shock from impact.
