The main objective of the Stress-less Shoe project was to develop plantar orthoses and footwear that minimizes the mechanical stress of locomotion for users with continuous and occasional overweight. The project joined a multidisciplinary team with complementary competencies consisting of 1 molded components manufacturing company (KBRINKA) and 2 footwear companies (KLAVENESS AND CALAFE), 2 scientific R & D entities (FADEUP, ESTSP-IPP) and 2 technological R & D entities (CTCP, INEGI). The Stress-less Shoe integrated synergically the knowledge and know-how of each of the involved partners in order to generate knowledge at the kinetic, kinematic and podological level during walking in the individuals under study, creating methodologies that support and sustain the proposed developments.
