Abstract
A sport shoe or rehabilitation shoe with a shoe sole with at least one insert part that is formed as a honeycomb body of elastic compressible material, the cells of which have central axes that run at least approximately perpendicular to the sole plane, has honeycomb cells in an area under a flexible zone of the forefoot which are provided with a surface area that increases, as seen in top view, from one side edge to an opposite side edge of the sole or midsole. This feature has the effect of achieving a stabilizing of the foot in running, especially in long-distance running, for example, in jogging, cross-country running, marathon running or the like, in the area of the forefoot, if the user's foot usually tends to tilt inward or outward (forefoot varus or valgus) in running. Further, the damping effect and the flexibility of such a shoe in the area of the forefoot are optimized.
