A shock-absorbing walk-aiding shoe includes a shoe main body, at least one elastic extensible belt and at least one connection member fixedly disposed on the elastic extensible belt. By means of the connection member fixedly disposed on the elastic extensible belt, the elastic extensible belt is fastened between an upper face of the shoe main body and a heel. When a user's foot treads onto the ground, the elastic extensible belt is elastically tensioned and the angle of the user's foot is changed to provide an elastic restoring force for the shoe main body to absorb the impact to the foot. Also, the elastic restoring force can be converted into an aiding force in lifting the foot away from the ground in the next move of the foot. Accordingly, the shock-absorbing walk-aiding shoe can provide a shock absorption effect and help the user in walking.
