Transparent Insole with Straps for High Heel Foot Pain
Solution Overview
Problem
Existing solutions for high heel shoe wear discomfort, such as insoles and inserts, fail to effectively stabilize the foot at both the heel and forefoot, are not adjustable, and are often bulky or visible, making them uncomfortable and aesthetically unappealing for prolonged wear.
Innovation Solution
A selectively removable insole made of flexible, deformable polymeric material with a slender configuration, featuring a toe strap, side strap, and ankle strap, designed to be transparent and minimally perceptible, providing comprehensive foot support and cushioning while fitting various shoe styles and heel heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing insoles and inserts are used to stabilize the foot, then foot support is improved, but the insoles are bulky or visible and aesthetically unappealing
Solution Approach 1:
The patent applies this principle by using a thin, flexible insole made of elastomeric material that conforms to the foot's contour. The insole is sufficiently thin to be inconspicuous when worn inside shoes, yet maintains structural integrity to provide foot stabilization through its molded arch support and heel cup features.
Solution Approach 2:
The patent applies this principle by providing differentiated support zones within the insole: a deeper heel cup for rearfoot stabilization, an elevated arch support zone for midfoot control, and a forefoot relief area. Each region has locally optimized thickness and rigidity to address specific biomechanical needs while maintaining overall aesthetic appearance.
2Reliability
If existing insoles and inserts are used to provide foot support, then foot comfort is improved, but the insoles are not adjustable and cannot accommodate various shoe styles and heel heights
Solution Approach 1:
The patent applies this principle by designing a universal insole template that can be used with various shoe styles and heel heights. The insole incorporates adjustable features such as repositionable adhesive sections and flexible material that allows it to adapt to different shoe interiors, making it suitable for both high-heeled and flat shoes without requiring multiple specialized insoles.
3Reliability
If existing insoles and inserts are used to stabilize the foot, then foot pain reduction is improved, but the insoles are not selectively removable and reduce shoe size
Solution Approach 1:
The patent applies this principle by designing an insole with selective adhesion features that allow the user to remove and reattach the insole as needed. The insole incorporates adhesive sections on the bottom surface that provide sufficient hold during wear but allow for deliberate removal, enabling users to take the insole out when desired while maintaining foot pain reduction benefits during wear.
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 effectively reduces foot pain and discomfort during high heel wear by stabilizing the foot, being adjustable, and maintaining a cosmetic appearance, suitable for prolonged wear without altering shoe size or appearance.
Implementation Method 1
The insole bottom surface is selectively coupled to the shoe insole with an adhesive material
Implementation Method 2
an insole platform member of a flexible, deformable, and polymeric material

AI summary
A selectively removable insole for high heel shoes comprising an insole platform member of a flexible, deformable, and polymeric material, a toe strap of a transparent polymeric material, and a rear strap member formed with a side strap member portion and an ankle strap member portion. Embodiments of the invention provide a transparent silicone sock compromising a self-supporting material that flexes, stretches and covers parts of the foot that usually get affected by common foot problems such as, by way of example and without limitation, skin irritation, blisters, skin stiffening, calluses, plantar forefoot pain at the forefoot, and metatarsalgia during fashionable, open or close toed, high heel shoe wear. Beneficially, a user can make any high heeled shoe, sandal, or boot that they already own or wish to purchase comfortable to wear for prolonged periods of time without foot pain or discomfort.
