The animation could not be loaded. The steps are listed below.

  1. Footwear combines a textile upper, an EVA midsole and a rubber outsole.

  2. Rubber outsoles and EVA midsoles are the parts recovered for surface use.

  3. Recovered material is prepared as granules.

  4. Granules and binder are formulated for the intended use.

  5. A lower layer of recovered rubber and EVA gives elastic support.

    In development

  6. Separate layers for elastic support, heat and wear.

    In development

  7. The layers are installed on site as one continuous surface.

  8. A track and field, ready for use.
