Golfers who use Ping irons can usually describe their equipment needs with a single letter.

“G” Series golfers, such as those who use Ping’s G25 irons, don’t mind larger-sized irons with more forgiveness that help them hit the ball higher and straighter. “S” Series golfers, such as those who use Ping’s S55 irons, prefer smaller-sized irons that offer more workability, versatility and a softer feel.

Somewhere in the middle falls the i-Series golfer, who needs more forgiveness than the S-Series irons can provide, but doesn’t want to play a set of irons as large the G-Series.

According to Marty Jertson, director of product development for Ping, the biggest challenge most golfers face is hitting their long irons high enough. That’s why Ping’s new i25 long irons are designed more like to the G-Series irons: they have longer blade lengths, wider soles and more offset, which helps golfers hit them higher, farther and closer to the target line on mishits. The irons also have thinner, more narrowly spaced stability bars in their cavities that make their faces livelier than their predecessors.

The short irons more closely resemble the S-Series irons, with shorter blade lengths and narrower soles for added versatility and less offset for more trajectory control. The stability bars in their cavities are thicker and wider-spaced, adding consistency and creating a softer feel at impact.


The most noticeable change between the new irons and their predecessors is their vertical Custom Tuning Port (CTP), an thermoplastic polyurethane (TPU) insert that is positioned much lower in the head, freeing up precious grams of discretionary weight that designers used to fine tune ball flight across the set. In the long irons, the weight was placed low and deep in the head, boosting ball speed by about 1 mph and lowering spin by about 100 rpms.

“Golfers will get more ball speed, more distance and more max height, especially from the 7 iron down,” Jertson said.

In the short irons, the weight was used to move the center of gravity lower and more forward, creating a flatter trajectory for better control.


The i25 irons are cast from 17-4 stainless steel and have Ping’s “Foggy Chrome” finish. They’re available in 3-9, PW, UW, SW and LW and come stock with Ping’s CFS shaft in Soft R, R, S and X flexes. The stock graphite shafts are Ping’s TFC 189i shaft, which is available in Soft R, R and S flexes.

The i25 irons will be available in mid-February for about $99 per club with steel, $125 with graphite.

  1. Personally I love the looks of the i20 and even more so the i25, PING is and always will be one of the best at what they do….making golf clubs, if you don’t like them, don’t use them it’s that simple you trout mouths

  2. Anyone know how the CFS shaft compares to Steelfiber 80 or 95 – or the c-taper lite? Looking for a somewhat lite shaft with some shock absorption and a slightly lower launch. With the CFS stiff I was launching 7-iron at about 24* with 5500 avg. spin rate. Any feedback would be appreciated.

    • That is exactly what I came up with last weekend. Some LA were just over 25*. It really concerned me, despite all the great things I have heard about the CFS. I am a low launch guy normally… Please let us know what you find if able.

    • I just went through a 2 month testing of irons. I am a 1.4 index, 62 year old, with a 95 mph driver SS. I hit various Mizuno models, the new Taylormade tour preferred models, 714’s, Titleist CB’s, the new Adams, all of the new Callaways (Apex, Apex Pro, X2Hot pro), the new Ping models (S55 and i25), the new Cobra’s (Bio+, last years AMP cell pro), etc.. I can’t think of anything from a major supplier that I didn’t hit, other than Wilson. I liked the i25 the most, and it wasn’t all that close. The i25s gave me a high penetrating flight that didn’t balloon, excellent distance, very smooth feel, and good forgiveness on off center strikes. The CFS shaft was OK, although I tended to hit the club left (my frequent miss, due to being a bit handsy). I hit the Aerotech i95, but found it feeling soft and mushy, and the ball did not carry well or fight the wind well. The fitter put me into the ZZ65, which he described as giving me the attributes of a DGS300, but with 109 grams instead of 130 grams (like in the DG). I found the ZZ65 to hit the ball plenty high, without ballooning, and the best distance of the bunch. The stiff tip also helped take some of the left out as well. I ordered the clubs the same day. If you don’t like the CFS, try the ZZ65 (which only comes in stiff). The second best club that I hit, by the way, was the Cobra AMP CELL PRO with a PXI 6.0.

      • Sean,

        I am a 50y/o 4.5 index looking at clubs now as well. I am a Mizuno fan and have MP-53’s (4-LW), Ping driver and 3-wood, Callaway 2-hybrid. Which Mizunos did you try and how did they compare to the Ping irons?


        • Sorry to be so tardy in responding. As I recall I hit the EZ forged and 825 Pro. I don’t recall the shafts that I hit in the 825P’s, but I think I hit the XP 105 in the EZ F’s. I recall thinking that the EZ Forged didn’t really feel all that good, and just didn’t feel very lively.

        • I should have added that I also hit the MP 59’s and I think that might be the best of the Mizuno family. I didn’t delve into the technology of the club, but the sweet spot feels a little springier and a little bigger as well. I know I hit the XP 105 Stiff in that club, but $$$ were a consideration.

  3. Placing my order for the I25’s tomorrow. Hope to have them with in the week being in AZ. Been playing the Adam’s CB1 for years and with age need a little more forgiving club. Will repost as soon as I’ve played them a few weeks.

  4. Ugly?! They look great. Was lucky to be first club in the uk to get to try them our pro is very good.. From address the 7 iron looks like an S55. I really liked them probably a little longer than my i10s. I suspect much of that might be due to shaft difference AWT vs CFS.

    Will definetly be interested in buying when these hit uk market in February. Now where to find £600?

    • Hi. Just hit the i25 iron. Fitting components were delivered to my fitting guy today. Hit the 7 iron with CFS Stiff side-by-side with same spec Anser iron. Ballflight on i25 was a tadd lower than with the Ansers. Also less spinny because I was hitting outside into the wind and i could see the shots with i25 having less trouble cutting through the wind. What struck me most was the feel and sound. When hit from the middle of the face there is almost no difference in feel or sound. Much softer than i20. When you miss the middle you can feel and hear the difference with the anser being softer. This was the same between full shots and chips. Distance there was no discernable difference. Anyhow for people that generally hit the center and want to know when they have hit it less then perfect the i25 will be a great match.

  5. Yes please.. Ugly like the i20s (which I have in my bag) but ugly or not they are the best irons so I will be getting them as soon as I can afford them..

    • You’d be doing yourself a real disservice if you ignored the competition and bought these. . . give them all a chance

  6. That i25 is going to be a silent killer. It’s gonna do great. You can just see it coming, it’s gonna do so well like the old Eye2 did back in the day.

  7. Ping….I love the new design attributes you’re moving to with these i25s, s55s, and the Rapture wood and driving iron. Fun clubs and I hope to be transitioning from my old Pings to these new i25 irons this year!!!

    • Classic “boring” looks dont mean cheap. Sorry they don’t have screaming reds or yellows or orange. I’m sure Playskool has a good looking set for you.

  8. I definitely preferred the looks of the i20 but I will say I was blown away by the looks of the s55 when I first saw them in person, so perhaps these too will look better “in the flesh.” The S series is probably still for me though – by far the most deceivingly forgiving players club in my opinion, I never did find any real benefit in the i20 than the s56 (own both), even as a 12 capper.

    • You should really hit the 55’s up against the i25’s then. I was considering the 55’s as well until i saw the carry numbers. My avg 7 iron with my MP 64’s carries 178. The avg with the 55’s was 176 and the avg with the i25’s……185. They aren’t as “pretty”…but the numbers were convincing for me.

  9. I do not, and have never owned Pings, but am going to seriously consider them this year. I have so much respect for their simplicity, functionality, and durability. I hit i20s this past fall, and was blown away with their combination of forgiveness and control. I can only assume at this point, that the i25s will be similar in their performance.

  10. The only problem with these clubs is They are pings. Sorry guys. They just yell “CHEAP!” To me. If i was paid to play them , maybe. They look like cheap pot metal. Any lash you throw at the ball with those clubs will fly high and straight. Great for weekend warriors, but they look boring and uninspiring. Do they actually manufacture their heads in the U.S.of A.? If so, ill tip my hat to that

    • I have buddies that play all different Ping products, and am blown away with how long they last, and how well they have aged. I don’t think that could be cheap in anyone’s book. I can understand that the look may not appeal to everyone, including me, but would never classify them as cheap.

    • Cheap?! Ping makes some of the most quality equipment in the game. Ping clubs are known to last forever– groves hardly show wear over the years because of the quality. I admit it takes time to get used to the looks (aside from the “S” line), but I would never call them cheap. The Ping staff players are the most underpaid players on tour, but still use the clubs because they know they are playing arguably the best equipment on the market. I used to be a Titleist guy and went through iron sets and Vokeys like nothing. Not to mention Ping has the most advanced club-fitting tools in the game. Don’t judge a book by its cover. Looks are one thing, but performance is FAR more important. If you want to talk about cheap, maybe you should move over to the TaylorMade threads…

      • Ping clubs last forever because they feel like crap. The cast steel they use is so hard you can’t dent em. They all sound so clicky and loud for an iron. In terms of performance, Myself and the two pros at my course all agree that they have hotspots in their irons. Seriously. I demo’d the S55 when the van came to my course, I hit one or two that rocketed off the face, hit the same as other swings. Are they forgiving? Very much. Are they durable? yeah, at the cost of feels.

        • I play forged irons currently, and while the i20 isn’t as soft as forged, they are still quite cushioned at impact.

        • The feel of the S55 is absolutely incredible. I have owned MP Mizunos, Titleist forged, and all the Callaway forged irons. The S55 feels better than anything I have hit, except, maybe, the Mizunos. If you miss it, not the best feel, but that is with ANY iron. They all feel different when mis hit, but when you hit it in the center, the S55 is as good as any forged irons I have ever hit. This comes from a forged snob. Try the S55, it is out of this world and can be played by anyone up to about a 15 handicap.

        • If you really think pings feel clicky and cheap then you haven’t tried the i25. Dont comment on a thread with info on a different product lol

        • Clicky!?? Ping’s are FAR from clicky. I have owned Mizuno MP 32’s, Taylormade RAC’s, Rocketbladez, Rocketbladez Tour, Burner HT’s, Scratch EZ-1 Forged irons and now I have a set of Ping i15’s. The Pings are easily the best irons I have gamed so far. When struck pure, they are very soft yet solid feeling for a cast club; very similar to a forged club. Not once have I ever had a clicky sound or feel off of these irons. Ping have that classic thud sound and are very soft yet solid at impact. Opinions are just that, opinions. Everybody has a brand alliance but that does not mean you have to be a troll and bash other manufacturers because you do not hit their products well. Remember, it’s the carpenter, not the tools, to an extent mind you.

        • The I25’s changed that for good. They feel quite soft really and are a vast departure from the old clicky hard feeling pings of old. Truth is perceived hard feeling clubs quite likely more to do with sound than actual feel as that is usually the case.. just like crunchy potato chips :)

        • You can criticize Ping clubs for being bland looking, or for not being the longest irons out there, but two things they are NOT is cheap and clicky.

          I think Ping’s attention to detail is on par with Titleist and perhaps even Mizuno.
