Feel-Based Green Reading vs Digital Feedback: Using BRK70® for Skill Acquisition

Putting is one of the most difficult parts of golf.

Even golfers with strong mechanics can struggle on the greens because reading slope accurately requires feel, visualization, experience, and consistency. A putt that appears straight may contain subtle elevation changes that significantly affect the break and starting line.

Over the years, golfers and coaches have developed different systems to improve green reading. In more recent years through a better understanding around the physics of green reading coaches have developed systems factoring in the core principles, notably how the factors of slope, angle, green speed and distance impact break.

One approach to green reading is utilizing the golfers feel of slope in their feet. This method of using your feet to feel slope has gained traction in recent years and has become a popular behavior attached to a variety of other elements to from part of a broader green reading process.

Golfers using their feet attempt to feel and estimate the size and the direction of slope beneath their feet. If you know these factors you can estimate the size of the break. This process can allows golfers to access a more tangible and structured green process.

What Is BRK70®?

BRK70® is a smart golf insole system designed to help golfers better understand green slope through real-time digital feedback.

The BRK70® smart insoles contain integrated motion sensors that measure:

• slope direction,
• side tilt,
• elevation changes,
• and green angle orientation.

That information is transmitted to the BRK70® mobile app, where golfers can view:

• digital slope readings,
• directional indicators,
• putting aim guidance,
• and visual green-reading feedback.

The system was designed as both:

• a green-reading technology tool,
• and a putting training aid.

BRK70® also allows golfers to measure putt distances, calculate aiming targets, and better visualize how slope influences the break of a putt.

How slope information is gathered and interpreted is important. That’s the key skill here within this approach to green reading. Your ability to be able to accurately determine slope size and direction determines the quality of your read.

BRK70® helps golfers train that same slope awareness by introducing measurable digital feedback from sensors inside the insoles.

Instead of replacing natural feel, BRK70® helps golfers compare what they sense beneath their feet with real-time slope data. Golfers can feel the slope, verify it digitally, and gradually improve slope recognition through repetition and feedback. Feedback is a key ingredient in the skill acquisition process which is typically missing with many golfers using such green reading processes.

The correct feedback loop can help accelerate skill develop and give you greater confidence on your reads on the course.

BRK70® was specifically developed to help golfers train and improve their natural ability to recognize slope more consistently.

Golfers using feel-based methods often spend years developing sensitivity to subtle elevation changes. BRK70® helps reinforce that process by providing measurable confirmation of the slope conditions they are experiencing in real time.

Over time, golfers begin developing a better understanding of:

• how different slopes actually feel,
• how subtle tilts influence putts,
• how speed affects break,
• and how to trust their reads more confidently.

For golfers who currently practice feet sensory methods, BRK70® can serve as a complementary digital feedback and training tool during practice sessions.

The goal is not to remove feel from putting — it is to help golfers refine it.

BRK70® is designed to help golfers improve green reading and putting consistency.

Feet/Feel-based methods train golfers to recognize slope through body awareness and repetition.

BRK70® complements that process by introducing digital slope feedback and real-time visualization into practice and training.

As golf technology continues evolving, digital green-reading tools may become an increasingly valuable part of putting development and player training.
