Meet the ZeroSole team
A better way to approach everyday offloading
Practising podiatrist Heather Smart and David Barton created ZeroSole, bringing together clinical experience and product development to address a gap they saw in everyday practice.
Heather Smart
Co-Founder, Director & HCPC Registered Podiatrist
Heather's experience as a practising podiatrist has been central to ZeroSole's development. Her clinical experience helped identify the problems the product was designed to address and continues to inform how it’s developed and used in practice.
David Barton
Co-Founder & Director
With a degree in podiatry, David brings a clinical background alongside his work in product development. He was closely involved in turning the original ZeroSole concept into a working product, developing and testing different silicone designs and helping shape the removable-cell system used today.
From an idea to a working product
The idea for ZeroSole came from a gap Heather and David kept seeing in everyday practice between temporary padding and more complex orthotic solutions.
They wanted to create a first-line insole therapy that sat perfectly in that middle ground.
Turning that idea into a working product took years of experimentation. They invested in CAD software and a 3D printer, while David developed and tested different silicone designs at home.
The breakthrough came when they successfully created a prototype with silicone hexagonal cells that could be mechanically removed by hand. This became the foundation of the modular system used in ZeroSole today.
The design continued to evolve through development and independent testing, but the core idea remained the same: an insole that could be adapted to the individual pressure point, that's long-lasting and durable to treat and prevent chronic conditions.
