The footwear includes a sole, a plurality of massage units, and a controller. The sole provides a support to the underside of a user's foot when the user is wearing the footwear. The massage units each include a channel, a plunger, a spring, and an actuator. The plunger is disposed within the channel and may slide within it linearly. The plunger has a shaft which terminates in an applicator, the applicator being round and configured to provide pressure to the user's foot. The spring is configured to maintain the plunger within a contact-position when at rest. This contact-position occurs when the plunger is maximally distal to the spring. The actuator is able to draw the plunger against the spring and release the plunger in repetition when energized, enacting a massaging action. The controller is able to selectively engage the actuators.
