A pneumatic or hydraulic massage sock including a unitary molded insole formed with one or more internal pump chambers for generating fluid pressure throughout the users gait, and a plurality of interconnected compression pads each containing an array of fluid feed tubes. The compression pads fold up and around the foot and calf substantially enveloping them in a low-profile sock-like configuration. An outer shell is worn overtop to maintain the compression pads against the users calf. The fluid feed tubes are in fluid communication with the pump insole to provide a self-compressive non-constricting deep-kneading, undulating (wavelike) pattern massage action up the leg in accordance with the full-length heel-to-ball-to-toe foot plant. The massage sock appears as a conventional sock so it can be worn with virtually any conventional pair of shoes. This provides effective unobtrusive relief for individuals with circulatory disabilities, diabetes, arthritis, etc.
