Mizuno's softest compression ball with 566 micro-dimples for longer flight
Mizuno Β· Golf BallsMizuno RB 566 Golf Balls
The RB 566 pairs Mizuno's softest compression with a unique 566 micro-dimple design engineered to slow the ball's descent after its apex, so it stays in the air longer. A large, high-energy core reduces driver spin and elevates launch for a stable, straighter flight, and the ionomer cover blends greenside feel with year-round durability.

Product questions
Frequently asked questions
Is the RB 566 good for slower swing speeds?
Yes. Its soft compression and large high-energy core help the ball launch and fly straight, and the micro-dimples help it stay in the air longer.
Why would faster swingers use it in winter?
Soft compression balls perform well in cold or soft conditions, so Mizuno recommends the RB 566 for all swing speeds in those conditions.
Can Grater Golf help me choose a ball?
Yes. Tell us your swing speed, typical conditions and what you want more of, whether that's distance, height or greenside spin, and we'll recommend the Mizuno ball that fits.
