Shoe Insole with Removable Strap for Heel Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High heels can cause discomfort, heel pain, and foot ulcers due to prolonged use, and there is a need for an accessory that provides protection and converts normal heel shoes into strappy heel shoes without requiring separate sets.
Innovation Solution
A shoe insole or heel protection pad with a removable leg strap made of cushioning materials like polyurethane foam or silicone gel, featuring apertures for attaching a strap that converts normal heel shoes into strappy shoes, providing cushioning and protection from blisters and calluses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a woman owns multiple sets of heel shoes for different occasions, then she can have both normal heels and strappy heels for various events, but it increases the quantity of shoes she needs to maintain and carry
Solution Approach 1:
The insole is designed to serve multiple functions: it provides cushioning for heel comfort, protects against friction and blisters, and acts as a base for attaching straps to convert shoes into strappy style. This multi-functional design eliminates the need for separate shoes for different occasions.
Solution Approach 2:
The insole is divided into two portions: a front portion corresponding to the heel of the foot and a rear portion corresponding to the posterior heel. This segmentation allows each portion to be optimized for specific protective functions while maintaining overall versatility.
2Duration of action of moving object
If high heel shoes are used for prolonged periods, then women can maintain their fashionable appearance and confidence, but it causes heel pain and foot ulcers
Solution Approach 1:
The insole is made of cushioning material such as polyurethane foam or silicone gel that is placed inside the shoe before wearing. This pre-positioned cushioning protects the heel from pain and ulcers during prolonged wear by distributing pressure and reducing friction before contact with the shoe occurs.
3Strength
If an insole is made rigid to provide structural support, then it can offer better protection, but it reduces flexibility and comfort during movement
Solution Approach 1:
The insole is made of flexible cushioning material such as polyurethane foam or silicone gel that conforms to the shape of the foot and shoe. This flexible material provides protection through cushioning and friction reduction while maintaining the ability to move naturally with the foot, avoiding the rigidity problems of hard materials.
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 solution offers comfort by reducing heel pain and preventing blisters and calluses while allowing users to convert their shoes without needing multiple pairs, enhancing both protection and style.
Implementation Method 1
The insole body may be made of polyurethane foam, silicone gel, or any other cushioning material

AI summary
The disclosure provides a shoe insole or a heel protection pad having a hole for a removable leg strap. The heel protection pad or insole comprises an insole body having a proximal end and a distal end, a pair of apertures configured near the distal end and a strap to pass through the pair of apertures of the shoe insole body. The proximal end is provided to be configured to conform to a heel of a user and the distal end is provided to confirm to the arch of the foot of the user. The insole body may be used to provide grip and prevent friction between the foot of the user and the heel shoe. The strap is configured to pass through the pair of apertures and detachably connect the strap with the shoe insole body.
