To evaluate the effects of grip torque on swing accuracy, we conducted a controlled experiment using a swing robot and an ultra high-speed camera to precisely replicate a player’s swing. The setup was consistent: identical club heads and shafts were used, with only the grips swapped between an IOMIC product and a leading competitor’s rubber grip.

When the club struck the ball at the center of the face, both grips performed similarly. However, the differences became pronounced during off-center impacts—specifically toward the toe. In these instances, the competitor’s grip exhibited significantly higher torque at the moment of impact. This increased torque causes the grip to twist more in the player’s hands, reducing control and accuracy.

While our proprietary Grip Torque Measuring Instrument predicted a push-out of 8.9 yards for the IOMIC grip, the actual test—with real swing dynamics and side spin—showed a deviation of 17.3 yards. In contrast, the competitor’s grip produced a dramatic 30-yard deviation under the same conditions.

In other words, the competitor’s grip resulted in nearly double the loss of accuracy.

This experiment underscores how torque-related performance differences become especially evident on off-center strikes. Thanks to our proprietary IOMAX material, IOMIC grips effectively suppress torque, delivering a more stable and consistent ball trajectory—especially under imperfect contact.

For golfers seeking greater accuracy and control, this clearly demonstrates that grip selection is just as critical as choosing the right head and shaft.
