A circulation therapy assembly includes a pair of boots that is each of the boots worn on one of a pair of legs. Each of the boots is comprised of a thermally insulating material and each of the boots has a height of at least 55.0 cm. Thus, each of the boots extends above a knee on the legs when the boots are worn. A pair of inserts is provided and each of the inserts is removably positioned within an associated one of the boots. Each of the inserts surrounds the associated leg and a corresponding foot when the boots are worn. Moreover, each of the inserts is comprised of a thermally conductive material. A pair of heating units is each coupled to an associated one of the inserts and each of the heating units heats the associated insert when the heating units is turned on. In this way each of the heating units heats the associated leg when the boots are worn thereby enhancing blood circulation in the associated leg.
