The SMART Assembly: the lie base (shaft) is fixed; all other components — face, back style, weights — are interchangeable. Sliding rear weights shift the centre of gravity (CG) along the sole. Moving CG changes face rotation at impact and stroke feel. Lie angle adjustable 65°–75° (continuous). Original range weights: 18g / 30g / 48g. Pro range weights: 5g / 15g / 30g. Key insight: the same stroke produces different face angles at impact depending on where the CG sits. A consistent miss-left may be a CG issue, not a stroke flaw. Most putter fittings address stroke arc only. Runner fits path first (lie angle + shaft position), then fine-tunes face rotation through weight adjustment. ## Brand & Story - [Runner x (RED)](https://www.runner.golf/pages/red): The story behind the Runner x (RED) collaboration and its social mission. ## Blog — Fitting Experience - [AI Fitting vs Expert Fitting](https://www.runner.golf/blogs/fitting-experience/ai-fitting-vs-expert-fitting) - [Expert Fitting: Where Data Meets Precision](https://www.runner.golf/blogs/fitting-experience/expert-fitting-where-data-meets-precision) - [Easy AI Fitting: The Smartest Way to Choose Your Putter](https://www.runner.golf/blogs/fitting-experience/easy-ai-fitting-the-smartest-way-to-choose-your-putter) ## Blog — Inside the Stroke (Product Education Series) - [Inside the Stroke 1: The Ergonomic Base of the Putter](https://www.runner.golf/blogs/inside-the-stroke/inside-the-stroke-1-the-ergonomic-base-of-the-putter) - [Inside the Stroke 2: The Shaft — The Spine of Your Stroke](https://www.runner.golf/blogs/inside-the-stroke/inside-the-stroke-2-the-shaft-the-spine-of-your-stroke) - [Inside the Stroke 3: The Grip — It's All in Your Hands](https://www.runner.golf/blogs/inside-the-stroke/inside-the-stroke-3-the-grip-it-s-all-in-your-hands) - [Inside the Stroke 4: The Face — Where Feel Meets Performance](https://www.runner.golf/blogs/inside-the-stroke/inside-the-stroke-4-the-face-where-feel-meets-performance) - [Inside the Stroke 5: The Backstyle — The Shape of the Putter](https://www.runner.golf/blogs/inside-the-stroke/inside-the-stroke-5-the-backstyle-the-shape-of-the-putter) - [Inside the Stroke 6: Adjustable Weights — Fine-Tune Your Feel](https://www.runner.golf/blogs/inside-the-stroke/inside-the-stroke-6-adjustable-weights-fine-tune-your-feel) ## Blog — News - [Runner Original V2 2026](https://www.runner.golf/blogs/news/runner-original-v2-2026) - [Runner x (RED): When Putting Goes Beyond Performance](https://www.runner.golf/blogs/news/runner-red-when-putting-goes-beyond-performance) ## Contact - [Contact](https://www.runner.golf/pages/contact): sales@runner.golf · www.runner.golf · @runner_golf (Instagram)
