This invention relates to an air-cushion type massager, which includes a massaging air bag, an air cushion to be positioned under a foot sole, and an air-delivering tube. The air-cushion type massager is generally used for people who always walk for long time. Users may put the massaging cushion on the lower leg or other affected area so that the air in the air cushion can be transmitted to the massaging air bag to inflate the massaging air bag due to the air cushion that is located under the sole being compressed by the weight of human body born by the leg that contacts ground. On the contrary, when the leg is raised, the air cushion is not subjected to the step-on pressure and restores to its original position so as to release air from the massaging air bag. As such, the affected area of the user can be massaged at the same time as the user is walking so as to alleviate the soreness and fatigue on the affected area.
