Make a Smaller Footprint with Sustainable Insoles
Sustainability at the Source
We believe in delivering the ultimate in insole comfort, performance, and support – while also providing sustainable insoles that both footwear brands and customers can feel good about. Our commitment to sustainability doesn’t just include using plant-based materials – it starts right at the source.
Truterra® Regenerative Farming Practices
Our materials sourcing partner, Susterra®, facilitates the Truterra® program, which is responsible for helping farmers transition to regenerative farming practices that promote carbon capture, soil health and coverage, and water retention.
Sustainably-Sourced U.S. Dent Corn
Through these regenerative farming practices, Susterra sources U.S. dent corn, a field corn grown and harvested specifically for purposes other than direct consumption, such as feed for livestock, renewable fuel like ethanol, and as an ingredient in plant-based biomaterials and consumer goods – like INSITE® Insoles.
Susterra Bio-propanediol
Susterra uses the dent corn to create Susterra bio-propanediol, which replaces some of the main petrochemical ingredients in traditional polyurethane, saving carbon emissions and non-renewable energy use. This remarkable compound uniquely enhances our foam with higher rebound and flexibility.
Transforming Manufacturing Practices
With our sustainably-sourced plant-based material, we then apply a sustainable manufacturing process to reduce our eco-footprint.

Cleaner Colors With Solution-Dyed Textiles
INSITE® top cover textiles are made with DuraDye™ fabrics, which produce bold, long-lasting colors using a cleaner, more sustainable solution-dye coloring process.
The DuraDye™ process adds color to the raw materials (PET pellets) as they are being melted and spun into yarn. This eliminates the need for a dye bath after the fabric is woven, resulting in 99% less water waste, plus additional power and CO2 savings.
Less Material Waste With Poured PU
INSITE® insoles with Contoura® and ArchRelief™ shapes use PU that is poured into a mold, rather than into sheets which are later cut. This does more than just support our patented ergonomic shape. It also has dramatic material savings, which in turn uses substantially less power and natural resources.
