Golf Shoe Outsole Traction Layout for Grip Without Turf Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf shoe traction elements focus solely on maximizing friction to prevent slips and falls, failing to optimize traction properties for golf performance and surface preservation, and are often uncomfortable or impractical for off-course use.
Innovation Solution
Golf shoes with optimally sized, shaped, and arranged traction elements that adapt to both on-course and off-course surfaces, providing customizable regional traction characteristics and minimizing shoe movement relative to the ground, while preserving surface quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional traction elements are designed to maximize coefficients of friction to mitigate slips and falls, then slip resistance is improved, but optimal traction properties for on course ground surfaces are not achieved
Solution Approach 1:
The patent applies local quality by providing different types of traction elements at different locations on the outsole. Specifically, spiked traction elements are positioned at a first location (heel region) to provide mechanical engagement with ground surfaces, while non-spiked traction elements are positioned at a second location (forefoot region) to provide friction-based traction. This spatial differentiation allows each region to have optimized traction characteristics for its specific functional requirements, resolving the contradiction between slip resistance and on-course performance.
Solution Approach 2:
The patent segments the traction element system into distinct types (spiked and non-spiked) that are distributed across different regions of the outsole. This segmentation allows independent optimization of each traction element type for its specific location, enabling the shoe to achieve both high slip resistance (through spiked elements at the heel) and optimal on-course traction properties (through non-spiked elements at the forefoot).
2Reliability
If traction elements are arranged to provide optimal traction stiffness, then shoe movement relative to ground surface is minimized, but surface damage to on course surfaces may increase
Solution Approach 1:
The patent applies local quality by strategically positioning spiked traction elements (which provide high traction stiffness through mechanical engagement) only at the heel region where they are most needed for stability during the golf swing. The forefoot region uses non-spiked elements that provide adequate traction with less aggressive ground engagement, thereby reducing surface damage in areas where aggressive traction is less critical.
Solution Approach 2:
The patent uses partial action by applying the more aggressive spiked traction elements only where absolutely necessary (heel region for swing stability) rather than across the entire outsole. This selective application provides sufficient traction stiffness to minimize shoe movement during critical moments while limiting the overall surface damage that would result from ubiquitous spiked elements.

AI summary
A golf shoe with a plurality of traction elements positioned around a central forefoot region and a central rearfoot region of the outsole of the golf shoe. The plurality of traction elements comprises: (i) a first set of traction elements arranged in a first outsole zone along a perimeter or edge of a medial or lateral forefoot region of the golf shoe, (ii) a second set of traction elements arranged in a second outsole zone along a perimeter or edge of a lateral or medial rearfoot region of the golf shoe, and (iii) a third set of traction elements arranged along a third outsole zone extending diagonally across a midfoot region of the golf shoe between the medial or lateral forefoot region and the lateral or medial rearfoot region. The third outsole zone includes a plurality of tracks extending across the third outsole zone.
