Edison Golf Updates the Most Versatile Sole in The Wedge Category

ROCKPORT, TX, September 19, 2023… Edison Golf is a company dedicated to revolutionizing wedge performance for recreational golfers. And part of that formula is that every EDISON 2.0 wedge is built around the patented Koehler Sole, a dual-bounce design that has been proven by thousands of golfers to eliminate the compromise of having different and specialized bounces and grinds in the bag.

The Koehler Sole is the only design to efficiently combine a high bounce angle in the front of the sole and a low bounce angle in the back of the sole so your wedges can handle a wider variety of lies and swing paths than any specialized grind. Proven for over 30 years with thousands of wedges bearing the brands Reid Lockhart®, EIDOLON®, SCOR™ and Ben Hogan®, the 2023 version in the EDISON 2.0 wedges have been further refined for even better performance. The high bounce leading portion of the 2.0 Koehler Sole has been widened a bit and the measured bounce angles have been tweaked. Combined with some nuanced shaping of the sole at the toe and heel, the EDISON 2.0 wedges have been made even more versatile.

How did Koehler get the idea for the Koehler Sole? In 1990, he took a golf trip to Scotland with his brother where he quickly found that his “tour design” sand wedge was fine for the bunkers but certainly not suited to the firm turf at the Old Course.

On his tour of Auchterlonie’s Golf Shop, he saw a grinding wheel and had an idea. He went back to the hotel to get his sand wedge and worked it over, creating the first crude iteration of the Koehler Sole. The “dual bounce” design worked beautifully during the rest of the trip with a very high bounce on the leading part of the sole and a very low bounce on the rear of the sole.

Upon his return, he ground and tested dozens of variations until he had it just right, and then filed a patent application on the design (which was awarded in 1994).

Though it has been known by many names (Dual Bounce Sole®, V-SOLE®) through its many iterations, tens of thousands of golfers have proclaimed the Koehler Sole to be the most versatile sole design in the wedge category, as it handles a wide range of turf conditions, sand textures, and swing paths. A recent story revealed the greatest golfer of the modern era has his own wedges shaped in a very similar way. He was only 16 years old when Koehler filed his patent on this innovative approach to sole design.

In addition to the Koehler Sole, the EDISON 2.0 wedges represent a quantum leap in wedge design, as they are the only wedges on the market specifically designed around a multi-year study of the way recreational golfers hit their wedges, as opposed to being designed for the extraordinary skills of elite tour players. They have the most efficient distribution of clubhead mass in the category to deliver better distance consistency, more forgiveness and improved spin.

Introduced in 2020, the original Edison Forged wedges significantly improved wedge performance by dramatically changing the way mass was distributed across the back of the clubhead. In the EDISON 2.0 line of wedges for 2023, an additional 14-17 grams have been positioned even higher in the clubhead, achieved by creation of a multi-level back design that optimizes smash factor across the face. This repositioning also creates a fresh and distinctive visual appeal to the product.

All EDISON 2.0 wedges are backed by the Company’s 30-Day Risk Free Trial. The Edison craftsmen will build you any EDISON 2.0 wedge and let you put it to the test on your course, hitting the variety of shots you face every round. If for any reason it’s not the best wedge you’ve ever played, Edison Golf will buy it back.

EDISON 2.0 wedges are engineered to odd-number lofts from 45 to 59 degrees and are custom built for each golfer from a wide selection of premium KBS® shafts and Lamkin® grips. Requests for even number lofts are met by tweaking the lower number clubhead. Shipping is always free, and discounts are applied on orders for full sets of three or more.

Past Meets Future With adidas Limited-Edition MC87 4D

CARLSBAD, CA – Technology and the aesthetics of golf footwear have evolved considerably since 1987, but there are some things that will simply remain timeless. Today, adidas is introducing the MC87 4D, a limited-edition spikeless golf footwear model that combines an upper inspired by the clean and classic looks from the adidas archives with the brand’s futuristic 4D midsole. The footwear is built on a gender-neutral last and will be available in a wide range of men’s and women’s sizing beginning September 21 on, the adidas app, and at select retailers.

Similar to the popular MC80 footwear that was recently announced, adidas’ MC87 4D is inspired by the classic styles from the 80s that are seeing a resurgence with golfers today. Specifically, the upper for MC87 4D draws inspiration from a model the brand first introduced in 1987 – the Tiverton – which featured wing tip styling, brogue stitch detail, and croc texturing all in a classic leather upper. MC87 4D builds off that original design to feature today’s premium, water-resistant leather upper, giving golfers the same classic look but with additional comfort. To push this design further, adidas included the adidas 4D midsole, the world’s first high-performance midsole crafted with light and oxygen. This is the first time the brand has featured the 4D midsole in a golf shoe. With one of golf’s signature team events happening in Rome next week, adidas included a special cobblestone sockliner as an ode to the streets of the city where sport has been played for thousands of years.

Based on years of athlete data, the single component design for the adidas 4D midsole is precisely tuned for controlled energy return. This intricate lattice structure printed with light and oxygen and using Digital Light Synthesis™ creates a futuristic design aesthetic but with purpose, as the responsive cushioning absorbs pressure from any angle and returns energy to the foot while also supporting movement where needed most. To complement the comfortable 4D midsole, the MC87 4D includes a rubber spikeless outsole with lugs to provide additional traction and grip for when golfers head to the course. The footwear will also come with a removable kiltie.

The limited-edition footwear will be available on, the adidas app and at select retailers beginning Thursday, September 21.

Sacks Parente Golf Unveils the Innovative Series 91 “The Duke” – a Classic-Style Masterpiece

CAMARILLO, CA – Sacks Parente Golf, Inc., a technology-forward golf company with a growing portfolio of golf products, including putters, golf shafts, golf grips, and other golf-related accessories, expands its repertoire of golf products with the introduction of the Series 91 “The Duke” putter that is now on sale at

A fusion of aesthetics and pioneering engineering, the Series 91 “The Duke” putter takes its inspiration from PGA TOUR Champions player Ken Duke. Known for his affinity towards a shorter blade length with a half mallet back, Duke asked SPG engineers to incorporate its technologies into this look. Duke, who recently won the Shaw Charity Classic, enthusiastically embraced SPG’s initial design. The resulting Series 91 “The Duke” putter integrates SPG’s proprietary technological advancements, marrying classic design with minimalist sophistication.

The Series 91 “The Duke” putter includes SPG’s three key performance technologies found in most SPG putters:

  • Patented Ultra-Low Balance Point (U.L.B.P.) – At the heart of SPG’s legacy is its patented U.L.B.P. technology, which means that weight is redistributed from the shaft and grip into the head. This technology enables a distinct feel, creating a smooth putting stroke that naturally squares at impact without a need to manipulate the head.
  • Weight-Forward Center of Gravity (CG) – As in all SPG putters, the Series 91 has maximized face-forward CG to ensure consistent rolls and minimized skidding, guaranteeing enhanced accuracy on the green.
  • High Moment of Inertia (MOI) – With an MOI of almost 5,000, almost unheard of in this putter size and shape, the chance of energy loss and off-center hits are few and far between.

SPG’s new Series 91 “The Duke” putter is fitted with 50 grams of tungsten distributed in both the toe and heel and towards the front of the head, resulting in 77% of the head weight in the heel and toe.

Most of the Sacks Parente putters contain the patented U.L.B.P. technology, face-forward CG, and ultra-high MOI. Test results from Golf Labs prove that these putters help golfers make more putts because of improved swing path, improved tempo, more distance control, better head release/closure, and more putter head feel.
