The ASICS Solution Speed FF 4 shoes has officially arrived for the 2026 tennis season, one of the premier choices for all-court players who prioritise speed, agility and fast transitions. Building on the success of the FF 3, this new version focuses on refining the balance between a weightless feel and the stability required for modern, aggressive baseline play.
Key Features of the Solution Speed FF 4
The FF 4 introduces several technical updates designed to help you cover the court more efficiently:
Updated FLYTEFOAM Midsole: The cushioning has been softened slightly to provide a more responsive, springy feel. It uses bio-based materials, making it lighter and more eco-friendly without sacrificing impact protection.
Enhanced SPEEDTRUSS Technology: This is the “engine” of the shoe. The updated truss system improves torsional stability (reducing unwanted twisting) and acts like a springboard to help propel you forward during sprints.
PRECISION-SOLE Outsole: Developed with AI-assisted data and player feedback, the outsole features a traction pattern that offers maximum grip where you need it most, while still allowing controlled slides on hard courts.
Improved Durability: A new PU (polyurethane) loop has been added to the upper’s medial side to protect the laces and high-wear areas – ideal for players who drag their feet during serves or wide volleys.
The Pro Connection: Lorenzo Musetti & More
ASICS has a star-studded roster for 2026, and the Solution Speed FF 4 is the centerpiece of their new Move Your Body, Move Your Mind campaign.
Lorenzo Musetti
The Italian sensation and Olympic bronze medalist is the primary face of the FF 4. Known for his flair, variety, and incredible footwork, Musetti’s game requires a shoe that can keep up with his constant direction changes and explosive sprints. You will see him wearing the flagship Digital Sakura (White/Pink) colorway throughout the 2026 season.

Belinda Bencic
The Tokyo 2020 Gold Medalist has returned to the tour and is another lead athlete for this model. Bencic has long preferred the Solution Speed series for its dynamic and stable feel, noting that the FF 4 helps her feel more confident when moving laterally.
Other Notable Pros
While players like Novak Djokovic (Court FF 3) and Alex de Minaur (who has been endorsing various ASICS speed models) are often associated with the brand, the Solution Speed remains the go-to for players who want the lightest possible footprint on court.
Is it right for you?
If you are a player who finds the ASICS Gel-Resolution too heavy or clunky, the Solution Speed FF 4 is your perfect alternative. It is designed for the speed player who attacks the net and relies on quickness rather than the stability player who stays planted behind the baseline.
What’s your opinion? Is this one of your best rated tennis shoes in 2026?
Find the new ASICS Solution Speed FF 4 for purchase at Tennis Warehouse, Tennis Warehouse Europe (get 10% discount using code TNERD10) or at Tennis Only (Australia). Or why not get it from Amazon.
You are incorrect about Lorenzo. He is not the face of the Solution Speed FF 4 but the face of the Gel-Resolutions, not the Solution Speeds.
Are t they significantly heavier than the FF3 now?
They are messing up the sizing. If you need a 10 better order a 10.5
