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 user's 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. ## Claims ### Claim 1 A therapeutic massage sock, comprising: a flexible insole formed with at least one internal pump chamber for generating fluid pressure upon a user's footstrike; a plurality of compression pads extending radially around said internal pump chamber, each compression pad comprising a flat, paddle-shaped member formed of an elastomeric material with a stem having a conduit in communication with said internal pump chamber, and an internal array of fluid flow channels molded in said elastomeric material, said array of fluid flow channels being in fluid communication with said internal pump chamber through the conduit of said stem, said array of fluid flow channels further comprising a plurality of integrally-molded fluid flow channels spaced parallel to one another across a flat of said paddle-shaped compression pad, and a plurality of valves wherein each valve resident in a corresponding channel of said plurality of fluid flow channels proximate the stem to control fluid flow therein; whereby said plurality of compression pads are adapted to fold up and around a user's calf to substantially envelope the user's calf so that the internal fluid flow channels extend upward from a user's ankle across the user's calf and collectively surround said user's calf, and said plurality of compression pads are adapted to provide a self-compressive undulating massage action up a user's leg when said user's footstrike operates said internal pump chamber to force fluid from said internal pump chamber upward along said fluid flow tubes. ### Claim 2 (depends on 1) The therapeutic massage sock according to claim 1, wherein said at least one internal pump chamber comprises a plurality of internal pump chambers for generating fluid pressure throughout the user's footstrike. ### Claim 3 (depends on 2) The therapeutic massage sock according to claim 2, wherein said plurality of internal pump chambers comprises an internal heel chamber coupled to an internal ball-of-foot chamber for generating fluid pressure in accordance with the user's heel-to-ball footstrike. ### Claim 4 (depends on 1) The therapeutic massage sock according to claim 1, further comprising a fabric shell worn outwardly of said flexible insole and compression pads for holding the compression pads in place. ### Claim 5 (depends on 4) The therapeutic massage sock according to claim 4, wherein said flexible insole and fabric shell are adapted to be worn inside a shoe. ### Claim 6 (depends on 1) The therapeutic massage sock according to claim 1, wherein said plurality of compression pads further comprises three compression pads extending radially from around the at least one internal pump chamber. ### Claim 7 (depends on 1) The therapeutic massage sock according to claim 1, wherein said at least one internal pump chamber is filled with fluid. ### Claim 8 A therapeutic massage sock, comprising: an insole including an internal pump for circulating air or fluid at each heel and forefoot strike; and at least one compression pad integrally joined to said insole, each of said at least one compression pads comprising a flat, flexible paddle-shaped member formed of an elastomeric material with a stem defined by a conduit in communication with said internal pump chamber and branched to a plurality of internally-defined fluid-flow channels molded in a flat of said paddle-shaped member, said internally-defined fluid flow channels further comprising a plurality of integrally-molded fluid flow channels formed in the elastomeric material spaced parallel to one another across a flat of said compression pad and in fluid communication with said internal pump, and a plurality of valves wherein each valve in a corresponding channel of said plurality of fluid flow channels to control fluid flow therein; said at least one compression pads deployable up and around a user's calf to substantially envelope the user's calf so that the internal fluid flow channels extend upward from the user's ankle across the user's calf and collectively surround said user's calf, whereby each heel and forefoot strike of a user's stride is adapted to initiate a self-compressive, non-constricting pattern of inflation of said fluid flow channels in a kneading patterned massage action spreading progressively upward along a user's foot and leg. ### Claim 9 (depends on 8) The therapeutic massage sock according to claim 8, wherein said insole is flexible and formed with a plurality of internal pump chambers for generating fluid pressure throughout a user's heel and forefoot strike. ### Claim 10 (depends on 9) The therapeutic massage sock according to claim 9, wherein said flexible insole is formed with an internal heel chamber coupled to an internal ball-of-foot chamber for generating fluid pressure in accordance with the user's heel-to-ball footstrike. ### Claim 11 (depends on 8) The therapeutic massage sock according to claim 8, further comprising a fabric shell worn outwardly of said insole and said at least one compression pad for holding said at least one compression pad in place. ### Claim 12 (depends on 11) The therapeutic massage sock according to claim 11, wherein said insole and fabric shell are adapted to be worn inside a shoe. ### Claim 13 (depends on 11) The therapeutic massage sock according to claim 11, wherein said at least one compression pad further comprises three compression pads extending radially from around the internal pump. ### Claim 14 (depends on 8) The therapeutic massage sock according to claim 8, wherein said internal pump is filled with fluid.
