High quality cellulosic material for an excellent performance; good alternative to the cellulosic materials traditionally used for the flexible part of mounting insoles. Specifically designed for long, pointed shapes and for all items requiring a very thin and elastic insole, it is only 0.6 mm thick. Exclusively made of pure cellulose fibers, certified, with no added dyes, it’s 100% biodegradable, 100% recyclable and pH 5.5-7.0. Thanks to its extraordinary features, it gives the shoe sole in which it is mounted a great elasticity with a thickness never reached before. When used for comfort insoles with cap, it makes the tip so stiff that it helps preventing its deformation over time.

When used in combination with NPU Green, it enhances the biodegradability level of the whole insole up to nearly 100%.
