High Heel Shank With Heel Depression And Ridge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high heel shoes cause unnatural weight distribution and posture, leading to discomfort, joint pain, and potential injuries due to excessive pressure on the toes and ball of the foot, which conventional modifications fail to adequately address.
Innovation Solution
A shank design for high heel shoes with a depression to receive the heel and a lateral ridge to prevent forward sliding, embedded between the insole and outsole, allowing for more natural weight distribution and posture by supporting the heel and distributing weight evenly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional high heel design is used, then heel height and style are achieved, but weight distribution becomes unnatural causing pressure on toes and ball of foot
Solution Approach 1:
The insole is modified with specific local features: a heel cup depression to receive the heel, a raised heel counter, and a shank extending from the heel cup. These localized structural modifications create different support characteristics in different regions of the insole, allowing the heel area to bear weight while reducing pressure on the toes and ball of foot.
Solution Approach 2:
The insole is divided into distinct functional zones: the heel cup depression for heel support, the shank region for midfoot support, and the toe area with reduced pressure. This segmentation allows each zone to independently manage weight distribution, preventing concentration of force on vulnerable areas.
2Shape
If conventional high heel design is used, then aesthetic appearance is achieved, but posture becomes compromised causing lower back pressure and joint pain
Solution Approach 1:
The heel cup depression and raised heel counter provide localized support at the heel area, encouraging proper heel placement and alignment. This local structural intervention helps maintain natural posture by supporting the heel in its correct position, thereby preventing the forward shift of weight that causes lower back and joint problems.
3Strength
If excess weight is placed on toes and ball of foot, then high heel structure is maintained, but foot cramping and arch compression occur
Solution Approach 1:
The shank is positioned to extend from the heel cup forward, providing structural support in the midfoot region. This segmentation of support functions ensures that the arch and ball of foot are supported by the shank rather than bearing excessive weight, preventing cramping and compression while maintaining the high heel structure.
4Device complexity
If conventional high heel design is used, then shoe simplicity is maintained, but repeated or prolonged use causes injury
Solution Approach 1:
Rather than fundamentally redesigning the entire shoe, the invention applies targeted local modifications to the insole: the heel cup depression, raised heel counter, and shank placement. These localized changes significantly improve weight distribution and injury prevention while maintaining the overall simplicity and aesthetic of conventional high heel design.

AI summary
A high heel shoe has an insole, an outsole, and a shank embedded between the insole and outsole, the shank comprising a heel portion with a depression to accommodate a user's heel, and a lateral ridge element in front of the heel portion that exerts pressure against the forward movement of a user's heel when worn. The shank further comprises a front portion sloping downward from the lateral ridge along the arch of the insole, which optionally is padded.
