Certified innovation since 1987
Every improvement in DIAN footwear stems from a rigorous process: research, testing, independent certification. In collaboration with INESCOP, the leading technology centre for European footwear.
Strategic alliance with INESCOP since 2019
INESCOP is the leading Technology Centre for the European footwear industry, based in Elda (Alicante). DIAN signed an R&D&I collaboration agreement in 2019 covering the development of new technologies, biomechanical testing and the certification of materials and processes.
This alliance is the technical foundation of our D'SEAL PRO®, MAXREACT® technologies and the FUNCTIONAL and ANTIbacterial certifications — all issued by INESCOP as an independent accredited body.
