Abstract: Articulated structure for the reinforcement of footwear articles, comprising a first rigid part (110), which comprises a sole (111) and an uprising portion (112) for the heel of the user, and a second and a third part (120, 130), arranged on opposite sides of said first part (110) with respect to the longitudinal center-line plane. Each one of these parts is separately joined to said uprising portion (112) of the first part (110) so as to obtain independent forward movements (FA, FB) and rearward movements (FC, FD) of a limited extent thereof. USE: Sports footwear, work-shoes and the like. ADVANTAGES: improved movement freedom of the foot, while maintaining the desired side support function unaltered; improved manufacturability of the footwear.
