Why Should You Get Custom Fit?

Matching golfers to the right shaft and components can add 10-30 yards to every iron in the bag while also improving accuracy. Playing better and having more fun on the golf course starts with clubs that are built specifically to match your individual swing.

5 Myths Debunked

    good enough

    Three swings on Mizuno’s Shaft Optimizer is all it takes to get started.
  • It takes too
    much time
    The Mizuno Performance Fitting System takes only 20 minutes.

    too much
    Mizuno custom irons do not cost more than our stock irons.

Mizuno Custom Fitting Is Like None Other

Mizuno has long been a leader in custom fitting for good reason. Not only is the Mizuno Performance Fitting System the quickest and most accurate system in the game of golf, but it also offers something thatvv no other fitting system can offer, the revolutionary Shaft Optimizer. In just a few swings, the Shaft Optimizer records five critical data points that make up your unique “Swing DNA”. A patented software program then takes the guesswork out of the fitting equation by analyzing that “Swing DNA” and quickly and easily identifying the perfect shaft, shaft flex, iron model, and set make-up that can immediately help you play better.

80% Of Golfers Are Playing With The Wrong Shaft. Are You?

Mizuno’s Shaft Optimizer will guarantee your clubs are customized specifically to your individual “Swing DNA” by measuring five key data points:

Swing DNA

Swing DNA measures Five Key Data Points to fit you with clubs perfectly tailored to your swing


Clubhead Speed measures how fast the clubhead and shaft are moving during the swing. Along with the other Swing DNA measurements, clubhead speed is important to determine the optimal shaft to maximize distance and trajectory.


Tempo measures how quickly the player transitions from the backswing to the downswing. It’s determined by the speed of transition from back swing to down swing and helps determine the weight of the shaft. Finding the correct weight improves timing for optimum energy release during ball contact.


Shaft Toe Down measures the bowing of the shaft in a downward direction during the downswing. Along with the Shaft Kick Angle, Toe Down is an important measurement in determining the proper shaft "bending profile" to help tighten dispersion with greater consistency.

Kick Angle

Shaft Kick Angle measures the amount of shaft forward bending during the downswing motion. Along with the Shaft Toe Down, Kick Angle is an equally important factor in determining the proper shaft "bending profile" to help tighten dispersion with added consistency.

Release Factor

Release Factor is a measurement of how and when the clubhead and shaft are releasing during the downswing motion. Depending on when you release the clubhead, earlier or later in the swing, determines the ideal shaft profile for better timing, which leads to better ball striking.
