Robot testing confirms these 5 irons greatly improve heel misses

Mizuno Pro 241 Irons blades

Robot testing confirmed golfers will see minimal distance drop-off on heel misses with the Mizuno Pro 241.


Go ahead and pick up the 7-iron in your bag and take a look at the wear pattern on the face. Unless your name is Tiger Woods or Moe Norman, there’s a good chance you’ll find some marks out on the heel or toe. Of the two locations, a heel strike is less common and comes from an inside path generally attached to better players.

We’re not saying a heel strike is the calling card of all better players but as you’ll notice from the list below, the Golf Laboratories swing robot highlighted several iron models geared for elite ball-strikers who miss it in the heel, including the impressive Mizuno Pro 241.

Of course, not every model on this list is a blade. For the game-improvement crowd, Ping’s G730 and XXIO’s 13 saw minimal distance loss on heel strikes when compared to geometric center impact. So, too, did the Blueprint S, a cavity-back model geared for the better player who still needs perimeter weighting for those mishits.

And if you’re wondering whether it’s better to miss it out of the heel or toe with your irons, the clear answer is the heel, according to the robot data. Across the 40-plus models tested, heel strikes averaged just 6.5 yards of distance loss versus 12.3 yards for toe misses. Now you know why better players tend to live in the heel when they don’t pure it.

(Methodology: All testing was conducted with a 7-iron at 80 mph — using the same shaft and attack angle — with six shots recorded from the geometric center and toe. The carry numbers below compare center and heel distances to achieve a carry delta.)

Ping G730 | 3.3 yards

PING G730 Custom Irons

Maximizing distance was the primary objective in PING’s longest and most forgiving iron to date, generating typical distance gains of approximately five yards from the flexing, hyper 17-4 stainless steel face. Flexing Face By employing hyper 17-4 stainless steel through heat treating, we thinned the face and optimized its overall structure to increase flexing and help lower the CG, delivering higher-launching shots with ball-speed gains and approximately five more yards of distance. Powerful Sound The cavity-back design is supplemented with the proven PurFlex cavity badge that enhances feel and produces a more powerful sound. Extreme Forgiveness The bigger head, more offset and wider sole in the investment-cast design increase the MOI in both axes, elevating forgiveness for improved stability and accuracy in this premium game-improvement design.

XXIO 13 | 4.2 yards

XXIO 13 Irons

The all-new XXIO 13 Irons deliver the ultimate in moderate swing speed performance. Their advanced, four-piece design has a remarkably low Center of Gravity for a satisfyingly high launch. 4-PIECE CONSTRUCTION XXIO 13 Irons feature a low Center of Gravity thanks to their 4-piece construction, which uses titanium faces and tungsten-nickel sole weights. That weighting, combined with our unique Rebound Frame structure which alternates stiff and flexible zones for added ball speed, gives you a satisfyingly high launch with incredible distance. REBOUND FRAME Rebound Frame uses alternating layers of stiff and flexible zones to enhance overall COR, creating an effect that acts like a spring within a spring. It adds ball speed and distance to every shot. On the Irons, a thinner face flexes more extensively while perimeter grooves etched deep into the interior of the Iron body add even more flex, especially for shots struck low on the face.

The pocket saves 10 grams of weight, which is re-allocated to increase the MOI and optimize the center of gravity position for more distance and trajectory control.
