The Carbon Grilamid LFT® is a polyamide reinforced with long carbon fibres that improve the elongation resistance properties and the rigidity of Grilamid®, without increasing its density when compared with the normal short fibres. This allows reducing the thicknesses of the shell and cuff, thus obtaining a light product but at the same time very performing. Impact resistance and solicitations are improved, allowing to keep intact the performance of the boots over time.
