A pressure sensor, e.g. for being arranged in the sole structure of an article of footwear, for measuring a pressure exerted by the wearer's foot. The pressure sensor comprises one or more pressure-sensing cells. Each cell comprises a first flexible carrier film and a second flexible carrier film, the first and second carrier films being attached to one another by a spacer film having an opening, a plurality of first electrodes arranged on the first carrier film and a plurality of second electrodes arranged on the second carrier film, the plurality of first electrodes and the plurality second electrodes being arranged in facing relationship with each other in the opening in such a way that the first and second electrodes may be brought into contact with one another when pressure is exerted on the pressure-sensing cell and that contact areas between the first and second electrodes increase with increasing pressure. The first electrodes are resistive electrodes. The plurality of first electrodes comprises a first group of electrodes and a second group of electrodes, the first and second groups of electrodes being arranged so as to interdigitate while delimiting gaps there between. The first carrier film carries conductive tracks that contact border portions of the first electrodes, which extend along the gaps, each conductive track defining an equipotential line in the respective border portion. One or more electrically insulating overprints are arranged on the first carrier film so as to cover the gaps. The overprints at least partially overlap with the border portions in which the first electrodes are contacted by the conductive tracks.
