BLACKROLL® COMPRESSION BOOTS - reimagined: with an even more comfortable fit, significantly longer battery life, and the option for continuous mains operation via cable. These boots can help reduce muscle soreness, heaviness and swelling in the legs. Inflatable trouser-style cuffs apply pulsating pressure to the legs. This relaxing compression massage promotes blood circulation and lymphatic flow, thereby supporting the removal of metabolic waste products. These boots may help to speed up recovery after working out or a long day on your feet. A travel bag is included for transport.
