The invention provides a shoe having an outer sole (16) moulded in rubber that undercuts the arch of the foot on the ground and extends upwards above the midsole level following the contour of the foot in a crescent shape. The undercut section is reinforced with ribs or webs (19) moulded into the arch area bridging the arch in a longitudinal plane. This provides support to the arch when stationary and in moderate usage yet allows progressive flexing to accommodate collapse of the arch during running or walking by partial stretching of the ribs or webs which then resume their original shape when pressure is released. |
