Lace Down Insole Systems for Slip-On Footwear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoelace systems require frequent adjustments and can make it inconvenient to slip shoes on and off, as they need to be tied, which can be uncomfortable and insecure for slip-on functionality.
Innovation Solution
A removable shoe insole with hook and loop fasteners on the bottom side to securely retain shoelaces underneath, allowing shoes to be slipped on and off without tying, by hiding the laces and converting the shoe into a secure slip-on design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional shoelacing systems are used, then the shoe can be securely fastened, but it requires frequent adjustments and tying which makes it inconvenient to slip on and off
Solution Approach 1:
The patent extracts the shoelaces from their traditional external positioning and relocates them underneath the insole. The laces are retained under the insole through slots and retention members, effectively removing them from the user's direct contact area while maintaining their fastening function. This extraction resolves the contradiction by eliminating the need for frequent tying adjustments while preserving secure foot retention.
Solution Approach 2:
The insole serves as an intermediary element between the shoelaces and the user's foot. By positioning the laces underneath the insole and using retention members attached to the insole, the system mediates the fastening function while preventing direct contact between the laces and foot. This intermediary approach allows slip-on convenience while maintaining reliable securement.
2Ease of operation
If lace-lock accessories are used to eliminate tying, then the need for tying is removed, but frequent adjustments or extra equipment are required to keep laces in place
Solution Approach 1:
The patent merges the lace retention function directly into the insole structure through integrated slots and retention members. Instead of using separate lace-lock accessories, the insole itself provides the retention mechanism. This merging eliminates the need for extra equipment while maintaining the ability to keep laces securely in place without frequent adjustments.
Solution Approach 2:
The insole serves multiple functions: it provides the traditional cushioning and support functions of an insole, while simultaneously serving as the retention mechanism for the shoelaces. The slots and retention members are integrated into the insole structure, allowing it to perform both comfort and fastening functions. This multi-functionality resolves the contradiction by eliminating the need for separate lace-retention equipment.
3Ease of operation
If laces are exposed on the shoe surface, then the traditional lacing function is maintained, but the laces are visible and may cause discomfort to the wearer
Solution Approach 1:
The patent extracts the shoelaces from their traditional exposed position on the shoe surface and relocates them underneath the insole. The laces pass through slots in the insole and are retained by members attached to the bottom of the insole, effectively hiding them from view and preventing contact with the wearer's foot. This extraction resolves the contradiction by improving comfort while the integrated slot system manages the structural complexity.

AI summary
The lace down insole system provides a removable shoe insole using hook and loop type fasteners as a method for retaining shoelaces beneath the insole. The lace down insole may comprise a top side and a bottom side with a plurality of “male” hook and loop type fasteners strategically placed on the bottom side of the insole, allowing the original shoelaces to be placed underneath the heel portion of the insole. This allows an efficient way for allowing shoes to have the ability to slide on and off without the need for tying the shoelaces.
