Smaller Footprint, Bigger Impact

Our Commitment to Sustainability

We believe in delivering the ultimate in insole comfort, performance, and support – and a huge part of that promise is helping to protect the planet while we do it. Our insoles offer industry-leading sustainable innovations and materials, without compromising on comfort, performance and support.

Making an Impact

We’ve also transformed the insole manufacturing process to reduce waste and increase efficiency, and we’ve adopted plant-based and recycled content for our foams to reduce our eco-footprint.

Supporting Sustainability With Plant-Based Foams


INSITE® plant-based insoles are made with a percentage of bio-based propanediol (PDO). This remarkable bio-PDO compound is not only derived from renewable, sustainable ingredients, but also enhances the foam with higher rebound and flexibility.

Our bio-PDO is made by suppliers using a glucose fermentation process from renewable industrial field corn. This replaces one of the main petro-chemical ingredients in polyurethanes – not as a filler or additive, but as a fundamental part of the polymer reaction.

Benefits of Bio-Propanediol

Based on a peer-reviewed life cycle assessment from 2019, comparing cradle-to-gate production of 100% bio-propanediol to the typical petrochemical alternative.





Environmental Savings of Solution-Dyed Textiles


Gallons of Water


kilowatts of power



Based on 1,000,000 insole pairs using solution-dyed over traditionally dyed fabrics per year.

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.
