Abstract (en)
[origin: EP2449904A1] Self-ventilating footwear, especially applicable to sports trainers, that comprises a sole with a chamber (4) in communication with the exterior by means of one-way valves (8) that allow air to exit the chamber (4) to the outside and prevent the ingress thereof towards the inside, this chamber (4) being in communication with the inside (5) of the footwear (1) via holes (6) made in the insole (3) that delimits the chamber (4) at the top, said holes (6), in combination with elastic patches (7), forming one-way valves that allow air to pass from the inside (5) of the footwear (1) towards the chamber (4), but not in the opposite direction, and therefore the loading of the foot (11) on the sole and the cessation of said loading give rise to a one-way circulation of air to the outside, via the chamber (4), providing ventilation to the inside (5) of the footwear (1) and therefore to the foot (11).
