Cut Sole introduces sharper leading edges and bevelled trailing relief, ensuring dependable turf interaction from every lie.
Completing the design, a Nickel Chrome Satin Brush finish reduces glare and reinforces the premium aesthetic.
The M-15, successor to the Mizuno Pro 245, offers a fully integrated progression of performance from long iron to wedge.
Each section of the set is designed with a specific purpose, creating smooth transitions in both shape and feel throughout.
At the core of the design lies the Contoured Ellipse Face, the latest development of Mizuno’s CORTECH technology, which defines the 4–8 irons. This multi-thickness forged construction, supported by a hollow body design, optimises ball speed and consistency while preserving the soft, responsive feel Mizuno players prize.
To improve launch and stability, tungsten weighting of 51g in the long irons and 50.3g in the mids has been strategically suspended within the head, helping produce straighter, more forgiving performance.
The long and mid irons pair a Grain Flow Forged 4135+ Chromoly face and neck with a stainless-steel back piece for additional rebound. The 9-iron to gap wedge transitions into a partial hollow 1025E Grain Flow Forged HD body with a stainless back, a construction that emphasises control, precision and manoeuvrability.
Refined sole geometry with added bounce encourages a cleaner entry and smoother exit through the turf, maintaining consistency across all course conditions.
Mizuno’s Harmonic Impact Technology and copper underlay reduce sound pressure around the 6kHz frequency, producing the soft yet solid strike that Mizuno players instinctively recognise.
Finished in Premium Nickel Chrome Satin, the M-15 brings a contemporary look with tour-informed shaping.
Together, the M-13 and M-15 mark the start of the Mizuno Pro Modern Series, joining the Signature Series (S-1 muscleback and S-3 cavity) to complete the Mizuno Pro line-up.
While the Signature Series continues Mizuno’s most traditional tour iron lineage, the Modern Series introduces new-generation solutions in speed, stability and shot-height control, all within the classic, compact profiles trusted by elite players.
The result is a clearer, more refined Mizuno Pro structure, one that offers golfers the freedom to match head design to playing style without ever losing the forged identity that defines Mizuno.
