Composite Midsole Golf Shoe for Flex and Rearfoot Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf shoes often sacrifice flexibility for stability and traction, leading to a rigid platform that does not allow for natural foot movement and comfort during golfing activities.
Innovation Solution
A golf shoe design featuring a midsole composed of two foam materials with different hardness levels and a fiber-reinforced composite plate, combined with criss-crossing traction tracks, providing stability, traction, and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the midsole is made of a single rigid material to provide stability, then stability is improved, but flexibility deteriorates
Solution Approach 1:
The midsole is divided into multiple layers with different material properties - a firmer lower layer for stability and a softer upper layer for flexibility. This segmentation allows each layer to perform its specific function independently, resolving the contradiction between stability and flexibility.
Solution Approach 2:
Different regions of the midsole are assigned different material characteristics. The lower portion uses firmer material for stability support, while the upper portion uses softer material for flexibility and comfort. This local differentiation enables simultaneous achievement of stability and flexibility.
2Ease of operation
If the midsole uses softer material to improve flexibility, then flexibility is improved, but stability deteriorates
Solution Approach 1:
The midsole structure separates the stability function into a distinct lower layer with firmer material, while the upper layer can be softer for flexibility. This segmentation prevents the stability function from being compromised when flexibility is prioritized.
Solution Approach 2:
The midsole combines multiple materials with different hardness characteristics - firmer material in the lower layer for stability and softer material in the upper layer for flexibility. This composite construction resolves the contradiction by allowing both material types to coexist in their respective functional zones.
3Stability of the object's composition
If a composite plate is added to the midsole to enhance stability, then stability is improved, but device complexity increases
Solution Approach 1:
The composite plate is integrated directly into the midsole structure, merging the stability enhancement feature with the existing midsole layers. This integration approach minimizes additional complexity compared to separate add-on solutions.
Solution Approach 2:
The composite plate is strategically positioned in the lower portion of the midsole where it provides maximum stability benefit. This localized placement ensures that the complexity is concentrated only where needed for structural support, rather than throughout the entire shoe.

AI summary
Golf shoes having improved constructions are provided. The golf shoes include upper, midsole, and outsole sections. The upper may be made of a soft, breathable leather material. The midsole includes an upper region formed from a first material such as a foamed ethylene vinyl acetate (EVA); and a lower region formed from a second material such as a foamed ethylene vinyl acetate (EVA), wherein the materials have different hardness levels. A fiber-reinforced composite plate such as, for example, a carbon fiber plate is disposed in the midsole. The composite plate has a molded three-dimensional shape to provide additional stiffness to the golf shoe, particularly in the rear foot region of the shoe. The outsole contains different traction members arranged in a precise geometric structure that helps provide improved stability and traction.
