Description
Mizuno RB 566 golf balls
A soft-compression ball engineered for longer carry and a higher, straighter trajectory. The Mizuno RB 566 (2024 model) is a two-piece golf ball built around a unique 566 micro-dimple design, a large high-energy soft core, and a durable ionomer cover. It is Mizuno's softest compression ball, delivering a satisfying balance of high launch, low driver spin, and all-round performance — ideal for golfers with low to mid swing speeds who want more carry distance without sacrificing feel.
Key Features
- 566 Micro-Dimple Design: A unique pattern of 566 micro- and D-dimples engineered to extend hang time past the apex of flight for added carry distance.
- High-Energy Soft Core: A large, low-compression core delivers a satisfying combination of ball speed, hot launch characteristics, and noticeably soft feel at impact.
- Ionomer Cover: A durable ionomer cover provides a responsive feel around the greens and outstanding all-year-round durability.
- Low Driver Spin for Straight Distance: Reduced spin off the tee promotes a mid-to-high, stable trajectory that keeps drives flying long and straight.
- Soft Feel Throughout the Bag: The softest compression ball in the Mizuno lineup, offering a buttery feel on putts, chips, and approaches without a meaningful loss of distance.
- Two-Piece Construction: A straightforward two-piece build optimised for distance and durability, making it an excellent value choice for mid- and high-handicap players.
- Pack of 12: Sold as a standard dozen, available in white.
Technology in Detail
Micro / 566 D-Dimple Design
The RB 566's name tells you exactly what is inside: 566 individual dimples arranged in a proprietary pattern that combines conventional dimples with smaller Micro Dimples. At mid and low ball speeds — typically past the apex of the trajectory — the lift effect of both the Micro and D-Dimples becomes fully effective, slowing the rate of descent and keeping the ball airborne for longer. The result is a steeper, more controlled descent angle that helps the ball hold the green on approach shots while adding measurable yards of carry distance off the tee. The D-Dimple (a dimple-within-a-dimple) contributes a more penetrating ball flight, making the design particularly effective for golfers whose swing speeds sit in the 75–95 mph range.
New High-Energy, Soft-Feel Core
The 2024 RB 566 introduces a redesigned large-diameter core that achieves two things that were previously considered trade-offs: a softer feel and higher energy output. Low compression (approximately 60 compression rating) allows the ball to compress fully even at moderate swing speeds, generating maximum ball speed for the swing without the stiff, clicky feel of harder distance balls. At the same time, the new core formulation promotes hotter launch characteristics so that the ball climbs quickly, reaches a higher apex, and then benefits from the dimple hang-time effect. Off the driver, this translates to fewer side-spin errors and longer, straighter shots; throughout the bag, it means a consistently soft, confident feel at every point of contact.
Stable Mid Trajectory & Low Driver Spin
One of the most common performance frustrations for average golfers is excessive driver spin that causes the ball to balloon, lose forward momentum, and veer off line. The RB 566's large, high-energy core is specifically engineered to reduce driver spin, promoting a stable, mid-height trajectory that flies straight and rolls out efficiently on landing. Lower spin off the tee does not mean lower spin everywhere, however: the ionomer cover retains enough greenside responsiveness to deliver useful spin on chips and pitch shots, giving players the confidence to attack pins from close range. This balance of low driver spin and workmanlike short-game spin makes the RB 566 a genuinely versatile all-round performer across every club in the bag.
Ionomer Cover — Feel & Durability
Rather than a urethane cover aimed at tour-level spin separation, the RB 566 uses a precision-formulated ionomer cover that prioritises two things: feel and longevity. The cover delivers a responsive, soft sensation off the putter face and a confident, slightly muted click off irons and wedges — exactly the feedback slower-swing-speed golfers look for. Ionomer is inherently tougher than urethane, which means the RB 566 resists scuffing from cart paths, wedge grooves, and the occasional tree far better than premium tour balls. For golfers who play frequently across all seasons, this durability translates directly into a lower cost per round without sacrificing the performance characteristics that matter most at their swing speed.
