Arneflex breathable polyurethane foam for insoles

Arneflex is a high-density open-cell polyurethane foam developed specifically for insoles.

Arneflex is the new high-density open-cell polyurethane foam with extraordinary breathability and absorption powers. It eliminates thermal sensitivity and has antibacterial components to help eliminate unwanted odours.

The foam manufacturing process and open-cell structure provide outstanding physical properties. In the foam industry, cell structure is a key factor for providing comfort. In terms of comfort, we are not only referring to flexibility, touch, and adaptability, but also thermal control and breathability.

Arneflex is ultra lightweight and offers optimum performance at low density with exceptional memory.

The high-density foam prevents fatigue as it provides greater shock absorption and better memory.

Arneflex is available in different densities from 80kg/m³ up to 200kg/m² and in various colours.

Arneflex foams are available in a wide range of colours and densities. We control the entire manufacturing process, which allows us to provide our customers with a customised and exclusive product, both in terms of format and colour.

What’s more, Arneplant works alongside various laboratories to guarantee technical features of the foams by performing tests on them to ensure maximum quality.

No CO2 is released during production, so the foams comply with all environmental regulations.

They also comply with the REACH.

Regulation 1907/2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals.

Arneflex is a high-density, fully-ventilated foam with excellent absorption and desorption properties, making it 100% breathable.


Arneflex, state-of-the-art foam that absorbs shocks and prevents fatigue.

With extra cushioning on the sole to improve health of your feet.

Arneflex 100% breathable PU foam

Arneflex foam is an innovative product resulting from studies by our R&D department.

We have developed the highest quality, breathability and durability for our Arneflex flexible foams thanks to the latest 3TPH technology. We continuousely control entire manufacturing process.

This lets us tailor and develop a fully-customised product in terms of density and colour for our customers, as well as offering a wide range of colours.

At Arneplant we develop solutions for our customers.

In a world of constant change, our products evolve and our ecological commitment becomes intrinsic to our new collection of more eco-friendly, recycled and breathable foams.
We never stop innovating and developing new formulations that lead us to high-performance, comfortable products which are designed to contribute to environmental sustainability Caring for and respecting the environment makes us grow as an organization. Our particular approach to expanding and modernizing our facilities is based on production which is committed to the conservation of resources. We want to respect the environment, and with our product innovation and eco-design proposals, we want to extend the life of our insoles by including more recycled or renewable materials to replace raw materials and improve recyclability. In a world of constant change, our products evolve and our ecological commitment becomes intrinsic to our product range.
We never stop innovating and developing new formulations that lead us to high performance, comfortable and, of course, environmentally friendly products.


In our new formulations we include bio castor plant oil. This plant needs the minimum resources to grow and is not for food use. In using it in our formulations we reduce our consumption of synthetic organic compound, which is an excellent way to promote sustainability.


One of the recycled components of our new foams is rubber. We use rubber from the footwear industry. The colour of the foams that include rubber in their formulation is peculiar in that you can appreciate the black specks in the material.


With the commitment to preserve the environment, Arneplant presents a new 100% recycled foam. We base its formulation on the total reuse of all waste, including that produced by the manufacture of our thermoformed foams and insoles. We innovate to close the circle of waste produced in our company


At Arneplant we recycle our foam waste to make it a component of our new eco-friendly foams. By incorporating recycled foam we provide extra ecological value, while maintaining the extremely breathable properties of our foams, which also provide extra padding for our feet.
