ABSTRACT:
Athletic shoes, particularly tennis shoes, are known which are provided with an ankle support in the zone of the arch of the foot (plantar arch) between the ball and the heel. In many such athletic shoes with ankle joint supports, the tread sole is fashioned with a corresponding constriction in the ankle region so that the inner ankle support is not shored up in the direction of the tread surface. To prevent such athletic shoes from buckling or bending flexurally in the ankle zone under high stresses, or even "break through", several discrete supporting profiles of varying heights are provided at the tread sole, the enveloping line of which on the free ends of these supporting profiles on the tread side lies at least approximately in the plane of the adjoining tread sole parts.
