Our production process

should be running in circles
An eco-friendly insole made from PU - is that possible?

Yes and no. 

In order to manufacture our insoles, we need polyurethane - a plastic that is used to make furniture, clothes, cars and a whole lot of other everyday life-things. 

Although it can reduce energy consumption and CO2 emissions (for example when used as insulation), polyurethane is a petroleum-based plastic that we cannot get around in our production - yet.

We are currently researching ways to substitute PU for green-TEC- filament: a compostable bio-polymer that consists of 100% sustainable materials.



3D printing technology to minimize production waste
Since conventional milling always produces an enormous amount of waste, we use a material-saving 3D printing process. This way, we only need exactly the amount of material necessary and your insoles already have a smaller climate footprint by design. When testing and further developing our soles, we always use recycled material to save resources. Waste that can’t be used for parts of new soles we try to re-use elsewhere - shredded, for example, discarded insoles can be recycled as playground surfacing.
Who said Electronics can only have one life?

If you send us your old soles, we will reuse the circuit boards they contain for new soles. This saves rare resources, plastic and materials - and as a token of our gratitude, we’ll give you a discount on your new pair!


The only thing left for us to figure out is how we can recycle the flexible sensor board; we are already working on a solution so that one day, our vision of a cycle economy may come true.

Packaging? Make it green!

We plan to make our packaging from recycled and environmentally friendly material - no need for any more plastic than necessary.
