Representative of the color red and its symbolism of the sun in Japan, the SOLUTION SPEED™ FF Tokyo tennis shoe expresses the athlete's burning passion to compete. This iteration is designed with a minimal construction that's topped off with an energized midsole response to help you track down hard to get shots. Designed with a FLEXION FIT® upper formation that wraps the foot with a sleek no-sew application, this shoe provides flexible support and an adaptable fit throughout the midfoot. Created to deliver excellent comfort, the P.H.F.™ (Personal Heel Fit) technology allows the shoe to mold to the natural shape of the wearer's foot for a customized feel. The lightest shoe on the ASICS Tennis roster, the SOLUTION SPEED™ FF model is layered with our FLYTEFOAM® midsole technology that helps promote a faster response with improved durability. Complementing the shoe's faster properties is the GEL® cushioning unit to attenuate shock from harsh impact, while sliding and braking. Constructed for a fast-paced game, the SOLUTION SPEED™ FF Tokyo tennis shoe is functional for supplying a responsive stride with increased cushioning properties.
