Continuing to bridge the gap between the ultra-stable PC Eclipsion and the ultra-light Sonicage, the Fusion Rev 4 offers the perfect combination of support, cushioning, and speed!
 
Featuring a bootie-constructed upper, now upgraded with the Fusion Wing, this design embraces the foot snugly, ensuring stability during aggressive side cuts. To enhance comfort, Yonex introduces a Power Cushion Plus midsole for a smoother, softer ride and efficient energy return during movement.
 
The redesigned single-piece outsole maximizes foot contact for improved court feel and torsional rigidity. The zonal sole pattern enhances durability in high-wear areas, while the more open lateral edge facilitates swift movement for fast players.
 
Upper: A lightweight, durable PU material wraps around Russell double mesh for comfort, support, and breathability. Additional protection around the toe and medial side guards against chafing and slipping on rough terrain. The shoe’s inner construction wraps the foot with elastic material for a soft, comfortable fit.
Midsole: Power Cushion Plus technology reduces foot fatigue, providing even more energy. Power Carbon midfoot mount maximizes stability while keeping weight down.
Outsole: Endurance rubber compound in a zonal tread pattern maximizes durability in high-wear areas, and the lateral edge improves glide on difficult courts. The R7 round sole facilitates a natural transition from heel to toe.
