Designed to follow the foot’s movements on the court, Babolat SFX tennis shoes allow you to move freely without sacrificing the durability and support needed by the most demanding players. The revolutionary Ergo-Motion midsole features a dual density midsole to equalize pressures on the foot during lateral movements and quick direction changes for effortless footwork. Move freely around the court in fluid motion with effortless footwork in the SFX. Upper: Superior Fit Experience (SFX) provides you with the best fit and feel for increased comfort. S-Shield for excellent durability, comfort and ventilation. Denser S-Shield material in high wear areas for extra abrasion resistance. Stitch-less tongue/vamp for a perfect flex of the forefoot. Anatomical collar shape and inner dampener toe protection. TPU counter for high heel support. A large toe box allows the foot to move freely and naturally. Midsole: Ergo-Motion dual material midsole adapts to the foot’s dynamic characteristics. During lateral movements and quick changes of direction, higher pressures are exerted on the lateral side (outside) of the foot. This is why the SFX Ergo-Motion midsole features 2 different materials to equalize pressure. REVAX (rubber and EVA) on the medial side is a more resilient and softer material to absorb higher pressures. EVA light on the lateral side of the midsole provides excellent cushioning. Kompressor System heel cushioning technology for maximum shock absorption and comfort. The Kompressor system is an innovative heel system made with EVA cushioning and TPR filled tubes. When the heel hits the ground, the shock is equally absorbed by the entire Kompressor system for consistent, dynamic response. 3D ergonomic shank to guide lateral movement and provide torsional integrity. Ergo-Motion multi-layer insole adapts to the player’s feet to offer unmatched first fit feel, long lasting cushioning and comfort with excellent support. The Ergo-Motion midsole consists of 6 layers: an anti-slip mesh top, memory foam for immediate step in comfort and custom fit, PU Ortholite® for long lasting cushioning, spring EVA for cushioning and rebound, 3D EVA hard cup for heel stability and support, and A soft EVA pad in the heel for additional cushioning and shock absorption. Outsole: Babolat’s exclusive Michelin all court outsole offers outstanding durability. Developed in collaboration with Michelin's R&D team, this outsole is specially designed to give players the highest performance over a longer period. The outsole design and structure are defined for optimized traction and ground contact on any surface. Flex grooves cut into the outsole promote natural foot movement.
