As evidenced by the line’s performance in Best Irons, Callaway had a winner on its hands with its 2021 Apex iron family. Thus, engineers faced what is arguably the best problem to have in golf club design: How to find areas for improvement in a winning design without “losing” in other areas.

Brian Williams, VP of Callaway R&D, spoke to this:

“We really have been on a journey for multiple years working with some of the world’s best players, getting feedback from them the whole way on things that we could do really in pursuit of perfection – how we can take a great product line and make it even better.”

“It’s us being calibrated with these players to be able to understand and see the things that they see. Their ability to perceive even the slightest change in designs is truly unbelievable and so we’ve been able to saddle up alongside some of these players on this journey that we’ve been talking about, the specificity that we use on these designs is next level.”

To see how the company navigated the paradigm (no pun intended), let’s dig in to the designs.

2024 Callaway Apex MB irons

Callaway’s “modern tour blade” was developed in collaboration with tour professionals and is designed to deliver efficient turf interaction (thanks to Dynamic Sole Design), optimum workability, and a classic feel in a one-piece, 1025 carbon steel forging. Callaway engineers designed the Apex MB line with progressive CG throughout the set — lower in the long irons for higher launch, higher in the short irons for a more penetrating trajectory.

As mentioned, the Dynamic Sole Design integrates “dual chamfer” (multi-angle) leading and trailing edges for efficient turf interaction.

Regarding the sole design, Williams said:

“This is the outcome of extensive work – I think we did 7 or 8 versions of this sole until we
had it perfected. We saw this Tour validated feedback where even when we had the slightest
thing off, they could pick it up and tell us how to fix it. We really changed that leading edge, the sharper leading edge, and this trailing edge chamfer for us gives a little bit of relief – it glides through the turf. All these versions have a similar approach, and we’ve worked on getting our balance to be very centralized – so we call it Dynamic Bounce, it’s variable as you move from heel to toe, and we have some additional toe relief. A player with very high speed they can have the toe down on impact, and that’s a way that we’ve really worked on the bounce.”

2024 Callaway Apex CB irons

Callaway touts an all-new forged construction in its 2024 Apex CB irons and its associated feel and workability. Forged from 1025 carbon steel in a five-step process, Apex CB ‘24 irons also feature MIM weighting in the toe and similar progressive CG and Dynamic Sole Design to the Apex MB irons.

2024 Callaway Apex Pro irons

Multi-material forged construction plus Callaway’s patented urethane microspheres create a new level of feel in the Pro series of Apex irons, according to the company. For the first time in an Apex iron, hollow body construction joins a 1025 forged carbon steel body.

Callaway touts an all-new progressive face design that delivers both increased distance and more precise distance control across the lineup. Long irons feature a forged 455 face cup for enhanced distance control, short irons have a 1025 forged face plate for enhanced control. Again, Dynamic Sole Design is featured with this iron.

2024 Callaway Apex UT irons

Callaway targets distance and versatility with the 455 forged face cup powered 2024 Apex UT irons. All the notable party guests are here as well: Dynamic Sole Design, urethane micropsheres, multi-material forged construction. Also worth pointing out: The new Apex UT is slightly more compact than the previous generation with a slightly shallower face.

Created for combo-ing

As with the previous generation of Callaway Apex irons, Callaway is again emphasizing combo set possibilities with 2024 Apex irons.

Discussing combo sets, Williams said, “We have the same weight across the entire family, and that opens a lot of opportunities for us. It’s a difficult challenge to develop a set with perfect gapping, and when you want to allow players to mix and match that’s a next-level complexity to solve. The team has worked on that, and I think we have something that’s incredible when you can just about swap any of these irons out.”
