How InStryde Works

Users can obtain their personalized insoles simply by scanning their feet with their phone—ushering in a new era of accessible, high-performance foot technology that caters to individual needs for enhanced mobility and comfort.

The Science Behind Custom Insoles

Custom insoles are designed based on the detailed research of foot biomechanics, specifically how the unique structure and movement of each person's feet affect their overall posture and walking pattern. This knowledge is crucial for creating insoles that effectively provide support and relieve pain.

Understanding the Underlying Science:

  • Foot Biomechanics: The human foot is a complex mechanical structure with 26 bones, 33 joints, and over a hundred muscles, tendons, and ligaments. Custom insoles are made to align with this intricate anatomy, giving personalized support that can correct biomechanical issues.
  • Pressure Distribution: By redistributing pressure away from areas of discomfort, custom insoles improve comfort for the wearer. They are shaped to match the curves of the foot, reducing stress on high-pressure points.

How Custom Insoles Work: Mechanisms of Support and Alignment:

  • Arch Support: By providing adequate support to the arches, custom insoles can prevent excessive inward or outward rolling of the foot - common problems that can cause pain and injury.
  • Heel Cupping: Custom insoles often have a deep heel cup to stabilize the heel. This feature helps absorb impact and maintain proper alignment of the foot.
  • Metatarsal Pads: These pads elevate and support the area behind the toes, relieving pressure from the ball of the foot which is beneficial for those with conditions like metatarsalgia.

Through precise engineering based on these scientific principles, custom insoles like those developed by InStryde can greatly improve comfort while promoting healthy foot function. They cater to individual needs by considering various factors such as foot shape, activity level, body weight, and specific health conditions.

Additive Manufacturing (AM) and Its Impact on Custom Insole Production

Additive Manufacturing (AM), also known as 3D printing, plays a crucial role in the production of custom insoles. It is a game-changing technology that allows for the creation of insoles specifically designed to fit individual feet and address their unique biomechanical requirements.

How Additive Manufacturing Revolutionizes Custom Insole Technology

Additive Manufacturing brings several key advantages to the table when it comes to custom insole production:

1. Precision and Customization

AM enables the replication of a foot scan with incredible accuracy, ensuring that each insole perfectly matches the shape and pressure points of the user's feet.

2. Material Innovation

With AM, a wide range of materials can be utilized to produce insoles with different levels of flexibility, durability, and support. For instance, InStryde has developed their own SmartCore™ meta-material specifically for this purpose.

3. Complex Design Realization

Unlike traditional manufacturing methods, AM makes it possible to create intricate support structures and designs that would otherwise be impossible to achieve. This leads to optimal comfort and performance for the wearer.

The Advantages Offered by Additive Manufacturing in Insole Production

The utilization of Additive Manufacturing brings numerous benefits to the table when it comes to producing insoles:

1. Speed to Market

Rapid prototyping facilitated by AM significantly reduces the time it takes to bring a design from concept to final product. This accelerated development process gives companies a competitive edge.

2. Waste Reduction

Compared to conventional manufacturing techniques where material is subtracted, AM is an additive process that generates minimal waste. This sustainability aspect is highly valued in today's eco-conscious world.

3. Customized Mass Production

One of the most exciting possibilities with AM is the ability to mass-produce customized products without the need for individual molds or tooling. This opens up new avenues for meeting consumer demands at scale.

The Roadblocks in Implementing Additive Manufacturing

While the potential of Additive Manufacturing in custom insole production is immense, there are a few challenges that need to be addressed:

1. Cost Efficiency

Getting started with AM for custom insoles may require a significant initial investment compared to traditional methods. However, as technology advances and becomes more widespread, the costs are expected to decrease.

2. Technical Expertise

Operating AM equipment and optimizing designs for printing demand a high level of technical proficiency. Training employees or hiring skilled personnel can be a hurdle for some companies.

By embracing the possibilities offered by Additive Manufacturing, companies like InStryde can deliver products that not only provide superior comfort but also enhance performance and reduce the risk of injuries. As this technology continues to evolve, it will undoubtedly reshape the landscape of custom insole production.

Design Optimization for Additive Manufacturing in Custom Insole Creation

The incorporation of design optimization in the creation of custom insoles is a crucial step that harnesses the full potential of Additive Manufacturing (AM). Design optimization refers to the strategic alterations and refinements made to a product's design to improve its functionality and manufacturability through AM processes. For custom insoles, this involves several key aspects:

Precision Fit

The design must account for an individual’s unique foot contours to ensure maximum comfort and effectiveness.

Material Efficiency

Optimized designs minimize material waste by using only what is necessary to provide support and durability, contributing to both cost-effectiveness and environmental sustainability.

Structural Integrity

Insoles must maintain their shape under repeated stress. Optimized designs leverage the strengths of AM materials while reducing the risks of deformations or breakage.


Aspects such as flex points, thickness variations, and support structures are meticulously planned to deliver targeted relief and correct biomechanical issues without compromising on comfort.

InStryde applies these principles by utilizing SmartCore™ meta-materials. The custom insoles are designed not just for fit and comfort but also for longevity, capable of withstanding high-friction environments due to meticulously optimized designs.
