Golf Shoe Insole With Localized Cushioning for Swing Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golfers face challenges in maintaining a consistent swing posture, leading to reduced accuracy and distance due to foot turning outward during weight shifting, which affects the hitting direction and power.
Innovation Solution
An insole for golf shoes with a second cushion portion supporting the side of the foot, formed with a higher rigidity and thickness than the first cushion portion, to stabilize the central axis of the swing and distribute body pressure effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If both feet turn outward during weight shifting in golf swing, then the swing path consistency is maintained, but the lower body support power is reduced and hitting accuracy decreases
Solution Approach 1:
The insole applies local quality by providing different cushioning characteristics at different foot regions. The first cushion portion (130) is positioned at the big toe area with specific cushioning properties, while the second cushion portion (120) is positioned at the little toe area with different cushioning properties. This localized differentiation allows the insole to control foot orientation and maintain proper swing posture while preserving lower body support power through targeted pressure distribution.
2Stability of the object's composition
If both feet turn outward during weight shifting, then the swing path remains consistent, but the upper body twisting motion becomes hindered and movement width increases
Solution Approach 1:
By providing asymmetric cushioning at specific foot locations (first cushion portion at big toe, second cushion portion at little toe), the insole locally influences foot orientation to maintain consistent swing path while allowing the upper body to twist naturally through proper lower body alignment.
3Duration of action of moving object
If feet turn outward during weight shifting, then the swing motion is maintained, but the hitting accuracy and driving distance are reduced
Solution Approach 1:
The insole uses localized cushioning portions at specific toe areas to control foot orientation during the swing motion. This local intervention ensures proper weight transfer and foot positioning, maintaining swing continuity while improving hitting accuracy by preventing excessive foot rotation that would compromise shot precision.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The insole improves posture stability and balance, fixing the central axis of the swing, enhancing accuracy and increasing the carry and driving distance while reducing direction angle.
Implementation Method 1
The second cushion portion may be formed of a gel material including one or more of thermo plastic elastomer (TPE), urethane, and ethylene-vinyl acetate copolymer (EVA).
Implementation Method 2
The first cushion portion may be formed of a gel material including one or more of styrene ethylene butylene styrene (SEBS) having viscoelasticity, urethane, and silicone.

AI summary
The present disclosure relates to an insole for golf shoes, which is inserted into the inside of a golf shoe and supports the sole of a wearer's foot. The insole includes: a main body on which sole of foot is seated; a first cushion portion which is provided on the main body and supports a portion of a front portion of the foot; and a second cushion portion which is provided on the main body, supports the remaining portion of the front portion of the foot, is formed in an area of a part where a little toe is seated, and supports a side of the front portion of the foot. With this configuration, it is possible to improve posture stability and balance by distributing body pressure during the swing motion. Also, the central axis of the swing can be fixed by fixing the center of body pressure, thereby improving sway and increasing the accuracy of hitting. As a result, it is possible to improve the carry and driving distance and to reduce the direction angle.
