High Heel Insole with Arch Protrusion for Achilles Tendon Exercise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High heels concentrate weight on the toe, leading to foot pain, joint damage, and spinal deformation due to uneven pressure distribution, which can result in long-term health issues such as blisters, calluses, hallux valgus, and spinal disorders like lordosis and low back pain.
Innovation Solution
The high heel design features a front end inclined surface, a middle end supporting surface, and a back end inclined surface with a protruding part that contacts the inner arch, dispersing pressure and exercising the Achilles' tendon with each step, thereby reducing stress on the toe and arch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the heel height is increased to achieve visual effects and emphasize femininity, then the aesthetic appeal is improved, but the weight concentration on the toe and instability of the ankle worsen
Solution Approach 1:
The insole is designed with different functional zones: a first insole part at the front end with a downward slope to reduce toe pressure, and a second insole part at the back end with an upward slope to support the arch and exercise the Achilles tendon. This local differentiation allows the shoe to maintain aesthetic appeal while addressing specific pressure points.
Solution Approach 2:
The insole configuration is designed in advance to prevent harmful effects before they occur. The downward slope at the front prevents weight concentration on the toe, and the upward slope at the back prepares the arch and Achilles tendon for the stress of high heel walking, preventing injuries before they happen.
2Shape
If the heel height is increased to provide visual effects, then the aesthetic appeal is improved, but the ankle stability and joint health worsen
Solution Approach 1:
The insole is divided into functional zones with different slopes: the front end slopes downward to stabilize the forefoot, while the back end slopes upward to support the arch and reduce ankle strain. This local differentiation improves ankle stability without compromising the overall heel height aesthetic.
Solution Approach 2:
The insole configuration is designed in advance to prevent ankle instability. The upward slope at the back end prepares the arch and Achilles tendon for the stress of high heel walking, providing preliminary support that maintains ankle stability throughout the walking process.
3Shape
If the front part of the shoe is narrowed to enclose the forefoot, then the aesthetic appeal is improved, but the pressure concentration on the toe and risk of deformity worsen
Solution Approach 1:
The insole at the front end is designed with a downward slope that distributes pressure away from the toe area. This local pressure redistribution allows the shoe to maintain a narrow, aesthetically pleasing front while preventing harmful pressure concentration on the toes.
4Shape
If the center of gravity moves to the front due to high heel height, then the aesthetic appeal is improved, but the spinal deformation and posture issues worsen
Solution Approach 1:
The upward slope at the back end of the insole is designed to preliminarily support the arch and exercise the Achilles tendon before the full impact of high heel walking occurs. This preliminary action helps maintain proper posture and reduces the risk of spinal deformation caused by forward weight shift.

AI summary
The present invention relates to a high heel for women, and particularly, to a high heel which not only prevents weight from being concentrated to the toe when worn but also absorbs shock to achieve walking comfort, and in which stress is provided to the arch of the sole to prevent deformation of the toes and exercise the Achilles' tendon such that joints are protected and the posture is corrected thereby preventing damage to the spine. To this end, a protrusion part 1 is formed at a part to support a back end of the arching of the sole, and an inclined surface 2 inclined downward from a back end of the protrusion part 1, which positions the heel of the sole to an end part of the high heel such that the Achilles' tendon can be exercised while walking.
