The Yonex Eclipsion 4 updates the support, flexibility, and power of the Eclipsion 3. In addition to the breathable PU protective mesh upper and Power Cushion+ in the midsole, the Eclipsion 4 has an expansive 3D Power graphite sheet in the midsole that increases stability and agility when pushing off or changing direction. The TPU stabilizer provides added cushion and security in the heel, and the one-piece outsole makes this Eclipsion 4 the most stable, all-court model yet. Worn by top players Stan Wawrinka, Casper Ruud, and Hubert Hurkacz, it’s safe to say that the Eclipsion 4 is the perfect high performance shoe.

TECHNOLOGY:

• POWER CUSHION: The YONEX Power Cushion absorbs shock then reverses the impact energy for smooth transfer into the next movement.Compared with urethane, the YONEX Power Cushion construction provides 3 times more shock absorbing power. When dropped from 7m above a Power Cushion sheet, an egg will bounce back 4m without damage.
• DOUBLE RUSSEL MESH: Double Russel Mesh is an ultra fine mesh that is extremely lightweight and durable. It provides eight times more air exchange for releasing moisture than ordinary mesh fabric.
• POWER GRAPHITE SHEET: A graphite plate is inserted under the middle portion of the sole to increase stability and reduce weight within the shoe.
• FEATHER BOUNCE FOAM: A new lightweight cushioning material designed to provide an added bounce with each step.
• SYNCHRO-FIT INSOLE: YONEX new Synchro-Fit Insole construction allows a closer fit between shoe and foot, keeping power loss to an absolute minimum to achieve smoother movement and quicker footwork. Fig1. Compared to conventional footwear, the mid to heel area on the insole is lifted to provide a closer-fit between shoe and foot. Fig2. By holding the heel more firmly against the insole, the gap between shoe and foot is reduced, improving comfort and ensuring the foot does not slip forwards inside the shoe.
• TOE ASSIST SHAPE: Improved Fit, preventing lateral movement in all directions.
• ROUND SOLE: The YONEX Round Sole ™ is designed to provide all-around support for quick and smooth footwork. The Round Sole ensures smooth movements and the transfer of maximum energy.
• HEEL CONTACT ROUND SOLE: Heel contact and round soleRounded heel design provides for a smoother heel contact and transition from heel to toe, plus a larger more rounded contact area for a smoother landing.
• DURABLE SKIN: Adaptive material that supports agile footwork with a stable yet flexible fit. The visually improved upper design technology increases durability whilst maintaining comfort for smoother footwork.
• 3D POWER GRAPHITE DRIVE: An expansive 3D graphite sheet is inserted in the mid-foot area; increases stability and agility to aggressively push off for faster footwork.
• ONE-PIECE OUTSOLE: One-piece outsole from toe to heel for more stability.
• HEEL STABILIZER: TPU is applied to the heel area for increased stability in the heel area when landing.
