The biomaterials in IMPRONTASANA® ECO-insoles


Well-being for your feet, respect for nature

When it comes to safeguarding our planet’s resources, the main factors involved are population growth, increased life expectancy and an ever-increasing demand for raw materials.

Sustainable development can help keep the constant demand for resources under control, introducing solutions that over time allow them to be reusable, while simultaneously improving quality of life and stimulating the circular economy.

Materials are defined as sustainable when they have a low impact on the environment and promote energy saving. Also called biomaterials, they are non-toxic and come not from the synthesis of chemical substances, but from natural, renewable and easily decomposable resources.



Renewable materials regenerate faster than they are consumed




Beech wood is an ecological material from renewable resources. It grows continuously in nature and, with sustainable management, guarantees unlimited availability.

It is moreover a strong, flexible and permeable material. Scientific studies have proven that in contact with humans, wood transmits positive energy and creativity, emanates warmth and naturalness, and evokes feelings of protection and relaxation.

ECO-Insoles which contain this material:



Coconut fibre is obtained from the mesocarp, the part that covers the fruit – until recently considered a waste material. Coconut fibre is extraordinarily resistant to rubbing, humidity, wear and is an excellent thermoregulator and thermal insulator, making it both breathable and comfortable. Due to these extraordinary features, it is considered one of the most reliable and indestructible natural fibres.

It absorbs shocks very effectively while maintaining its original shape. Being a material of plant origin, it is completely recyclable and reusable. Processing it requires little money or energy.

Cork is one of the most durable natural organic materials from oaks, extraordinary self-regenerating trees which preserve biodiversity and balance in the ecosystem.

For this reason, using cork does not damage nature and it is produced without chemicals. This material is biodegradable and can be recycled without polluting the environment. It is naturally antibacterial, hypoallergenic, breathable, light, resistant to humidity and has a high mechanical resistance.

Crops of these vegetable fibres are highly valued for their contribution to environmental sustainability. In the process of growth, kenaf uses carbon dioxide – a contributor to the greenhouse effect – as a raw material and releases a considerable amount of oxygen into the environment.

It is an eco-sustainable, renewable material with high breathability, naturally antimicrobial, hygroscopic and thermoregulatory.

The farmers from the Val d’Ultimo in South Tyrol collect the wool twice a year. The sheep graze all summer on the alpine meadows 2,000 metres above sea level and their wool is naturally processed without the use of chemicals.

The felt is obtained from shorn, washed and carded wool; it is then combed, with the fibres untangled and all placed in the same direction, through a process called felting. Sheep’s wool has thermoregulatory functions and, while absorbing water vapour between the fibres, has a water-repellent surface. Untreated wool is therapeutic and conveys tranquillity. The virgin wool felt is composed of 100% natural fibres and at the end of its life the product can be composted. Wool felt is a sustainable and renewable material.

Recycled polyurethane agglomerates are versatile, modern and safe. They are used in a wide range of applications to create various consumer products and are critical to making our lives more convenient, comfortable and environmentally friendly. The recycled polyurethane industry continually strives to improve the end-of-life phase of waste products to transform them into sustainable materials. Every year, thousands of tonnes of polyurethanes are recycled, recovered and reused for wide-ranging uses in production.
