Both lightweight and flexible, the GEL-GAME™ FF tennis shoe is multi-functional for all-court players. Preserving its excellent support properties, our focus this season was to improve the shoe's ventilation and flexibility. Featuring an open mesh design on the upper to improve airflow and keep feet cool, this shoe is complemented with synthetic leather overlays and a PU (polyurethane) film that offers improved stability when making abrupt transitions. The TRUSSTIC™ technology in the midsole generates better stability on the court. At the same time, the FLYTEFOAM™ technology in the midsole helps provide lightweight cushioning.Additionally, the improved outsole offers better flexibility and durability.
