ABSTRACT:
A sole pad with shock-absorbing and massaging effects is provided with, on the underside thereof, a mounting recess including a first and second receiving cavities that are connected to each other by a connection groove. A pressure transmitter has a first massaging ball and a second massaging ball filled with liquid and in communication with each other by way of a tubular portion. The pressure transmitter is securely housed in the mounting recess. The first and second receiving cavities have respectively a through hole so as to permit the massaging balls of the pressure transmitter to outextend the surface of the sole pad for contact with a wearer's foot. Liquid filled in the pressure transmitter can move between the first and second massaging balls by way of the tubular portion when the wearer's foot exerts unbalanced pressure on the sole pad in walking so as to effect shock absorbing and massaging purpose at the same time.
