Transforming Mobility for Leg Amputees
Rediscover natural mobility with our innovative carbon fibre inserts—designed for confidence and comfort!
Our mission is to facilitate and enhance the natural mechanics of walking.
Founded by David Judd, a lower limb amputee with over six years of personal experience, we have developed and manufactured this innovative product that has transformed the gait of amputees.
Meticulously designed, these inserts provide essential support for natural, comfortable, and confident movement, empowering users to reclaim their stride and independence.
The Walk Sure carbon fibre shoe insert is specifically engineered to help users maintain a natural walking pattern characterised by a "heel-on, sole, toe-off" motion.
This design aims to support users in preserving this stride consistently over prolonged use.
These four photos show how the heel on–toe off is exactly the same on both feet, giving you precise continuity each and every stride, time after time, mile after mile, watch the video below of David wearing the Carbon Fibre Shoe Insert.
Our Mission
To provide a lightweight, effective, and life-enhancing solution to every leg amputee around the world — empowering confident, natural walking without the need for costly or complex prosthetic changes.
We believe that every step should feel strong, balanced, and sure — because every amputee deserves to walk with confidence.
Whether you’re newly amputated, an experienced prosthetic user, or a healthcare provider — we’re here to help. Our patented carbon fibre inserts are now available globally.
Walk stronger. Walk further. Walk Sure.
The Problem That Sparked a Solution
Through careful self-observation and discussions with prosthetic experts, it became clear that the issue was due to the short keel design of the prosthetic foot, limiting its ability to replicate a full, natural stride. A long-keel foot would help — but switching entire prosthetic legs just to go for a walk wasn’t practical, and risked injury.
This sparked an idea: What if there was a way to enhance stride without changing the prosthetic leg?
From Workshop to Walkway
The first prototype was a simple plywood insert, hand-cut using a coping saw. It snapped after just a few steps — but those few steps were a revelation.
Next came a steel version: strong, but far too heavy. It created an unnatural pendulum effect, making the prosthetic leg feel unstable.
Then came the breakthrough: carbon fibre — a material as strong as steel but incredibly light. A custom insert was created in partnership with a specialist in Norwich, and for the first time, it enabled a full, natural stride. That very same insert is still in use five years later.
A Simple Solution That Works
The carbon fibre insert not only supports proper heel-on toe-off motion but also mimics the function of the Achilles tendon — something every leg amputee loses with their limb. The result is an insert that improves balance, comfort, and confidence with every step.
One experienced prosthetist described it as:
“The simplest, most effective solution I’ve seen in 30 years of working with amputees.”
Encouraged by both medical professionals and amputees alike, our founder patented the design — and Walk Sure Ltd was created to share it with the world.
