Sports Sock Sole Guide Pads for Foot Roll Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports socks fail to provide adequate comfort and support the natural rolling movement of the foot, leading to insufficient damping of impact energy during pronation, resulting in increased load on the foot and locomotion apparatus, particularly in cases of underpronation and overpronation.
Innovation Solution
The sock features a sole region with a heel guide pad and a ball guide pad arranged parallel to the natural roll line, providing stable guidance and support across the foot's movement, with the heel guide pad extending over the entire heel region and the ball guide pad extending to the toe region, both designed to mimic the foot's natural arc shape, and optionally incorporating perforations and material reinforcements for enhanced comfort and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the sole region is subdivided into several independently acting functional regions, then the damping of impact energy is improved, but the wearer comfort deteriorates due to slipping and insufficient hold
Solution Approach 1:
The patent combines multiple independently acting functional regions into a unified one-part design where the entire sole region has a continuous structuring as a function of a roll line. This integration ensures secure hold and control of foot roll while maintaining energy damping through the coordinated structure across the entire sole region.
2Stability of the object's composition
If the entire sole region has a design with structuring as a function of a roll line, then the control of foot roll is improved, but the wearer comfort deteriorates due to rigid wearing sensation and pressure sites
Solution Approach 1:
The patent applies different structuring densities and material properties to different regions of the sole. The structuring as a function of the roll line provides guidance where needed, while varying the degree of structuring locally allows for flexibility and comfort in specific areas, preventing rigid wearing sensation and pressure points.
3Stability of the object's composition
If a pronation support is added to the sole region, then the support of natural roll movement is improved, but the device complexity increases
Solution Approach 1:
The patent integrates the pronation support function directly into the overall sole region structuring rather than adding it as a separate component. The entire sole region is designed with a one-part structure that incorporates roll line guidance and pronation support features, eliminating the need for additional separate elements and reducing device complexity.

AI summary
A sock, in particular, a sports sock, comprising a sole region (10), which has a toe region (1), a ball region (2), and a heel region (3). The sole region (10) is provided with a heel guide pad (4) and a ball guide pad (5), which lie substantially parallel to a longitudinal roll line (6) of the foot of the wearer of the sock.
