Uniquely shaped cover enhances the shaft's performance. The front allows for greater flexibility, while the wider surface transfers power to the shuttlecock. The increased width stabilises the racket head, preventing the shaft from twisting.

Medium stiffness allows for some bend in the racket during a hit, which in turn translates to greater power and depth in the shot. This feature is particularly useful during exchanges with an opponent, where strength and speed are crucial. Medium stiffness also provides the necessary control over the racket. As a result, the player can be confident that every shot will land exactly where intended.

The key feature of the YONEX Astrox 88 D Play 4U racket is its isometric head shape. This design increases the area where the main and cross strings intersect. What does this mean for the player? A larger sweet spot. As a result, even slightly inaccurate shots have a chance of success.
