PING PLD Milled 24 Ally Blue 4 putter
The timeless Ally Blue 4 is a bold statement in premium putter engineering. Its eye-catching matte black finish immediately sets it apart on the green, while its fully machined, three-piece construction — combining an aluminum body, aluminum hosel, and 304 stainless-steel sole plate — delivers an exceptionally high MOI mallet that is both forgiving and effortless to align. Designed for golfers with a strong arc stroke, the Ally Blue 4 rewards those who demand the finest craftsmanship and a truly premium look and feel from their short game equipment. Every PLD Milled model undergoes more than four hours of comprehensive milling, ensuring that every curve, surface, and radius is meticulously shaped to meet the exacting standards of precision associated with the PLD program.

Technology in Detail
Three-Piece Multi-Material Construction
The Ally Blue 4 is an all-new fully machined design that brings together three distinct materials in perfect harmony. The lightweight aluminum body and aluminum hosel significantly reduce weight in the upper portion of the head, allowing PING's engineers to redistribute mass precisely where it matters most — low and to the perimeter. The 304 stainless-steel sole plate provides structural integrity and contributes to the putter's deep center of gravity. Together, these three components create one of the highest-MOI mallets in the PLD Milled lineup, delivering exceptional forgiveness on off-center strikes and a rock-solid, stable feel through impact.
Deep AMP Face Milling (Aggressive Milling Pattern)
Inspired directly by feedback from PING's tour staff, the deep AMP (Aggressive Milling Pattern) face technology is the defining performance feature shared across the entire PLD Milled range. Unlike conventional face milling, the AMP grooves are machined to a greater depth, producing a noticeably softer feel at impact without sacrificing the feedback or responsiveness that low-handicap players demand. The pattern also plays a critical role in speed control — regulating the energy transfer between club and ball to help golfers dial in their distance on fast or slow greens with consistent, repeatable results.
Exceptional MOI and Forgiveness
MOI — moment of inertia — is the measure of a clubhead's resistance to twisting on off-center impacts, and the Ally Blue 4 has been engineered to maximize it. The square footprint combined with the strategic placement of lightweight aluminum and denser stainless steel creates a mass distribution that resists unwanted twisting far better than conventional single-material mallet designs. The result is a putter that keeps the face square and ball speed consistent even when you catch the ball slightly towards the heel or toe. For golfers who struggle with distance control on mishits, the Ally Blue 4's high-MOI design is a genuine performance advantage.
Alignment and Address Confidence
The Ally Blue 4 features a square footprint and full-length top alignment aid that makes squaring the face to the target line intuitive and effortless at address. The bold matte black finish on the body and hosel creates a stark, clean contrast that frames the ball beautifully and eliminates visual distractions. PING's design team has specifically engineered the Ally Blue 4 so that golfers with a strong arc putting stroke can set up with total confidence, knowing the putter's geometry and visual cues are working in their favour from the moment they step over the putt.
Tour-Proven Quality and Premium Craftsmanship
Every PLD Milled putter is a showcase of PING's commitment to manufacturing excellence. The Ally Blue 4 undergoes more than four hours of CNC milling time, with skilled technicians precisely shaping every surface, curve, and radius to achieve the flawless quality and premium aesthetic that defines the PLD program. Five tour-proven models form the 2024 PLD Milled lineup — the Anser, Anser 2D, DS72, Oslo 3, and Ally Blue 4 — each representing the culmination of PING's decades of putting research and their ongoing collaboration with the world's top professionals. This is not a production-line putter; it is a hand-crafted performance instrument.
Strong Arc Hosel Geometry
The Ally Blue 4's short slant hosel has been purpose-designed for golfers who play with a strong arc — those whose putter face opens significantly on the backswing and closes through impact. The hosel geometry positions the shaft in a way that naturally complements this stroke type, promoting a smooth, on-plane arc and reducing the tendency to push or pull putts. Golfers who have previously struggled to find a putter that suits their natural motion will find the Ally Blue 4's engineering aligns perfectly with a strong arc putting style, helping translate a natural stroke into consistently holed putts.

Shaft
The Ally Blue 4 ships standard with PING's own proprietary Matte-Black Stepless Steel shaft — a patented, single-piece steel shaft finished in a matte black coating that eliminates the steps found on conventional steel shafts. The stepless design provides a smooth, consistent feel throughout the stroke and a clean aesthetic that perfectly complements the putter's matte black body and hosel.
Standard Grip
The standard grip is the Golf Pride PING PP58 Black Midsize — a midsize pistol-profile grip that offers an ideal balance of comfort and face awareness. The PP58 Midsize encourages a light, tension-free grip pressure, helping golfers maintain a consistent putting stroke and improve their distance control. Available in right-hand and left-hand configurations across lengths of 33″, 34″, 35″, and 36″.
