The Therabody RecoveryAir JetBoots Large is a compression leg massager that works cordlessly. The cushions are built inside the massager, so you don't have to prepare anything for the treatment. Put your legs in the massager. The various air pressure levels will allow your blood flow to improve and your muscles to recover from stiffness or tiredness faster. Adjust the massage to your wishes with the 8 different intensity levels. The special FastFlush technology ensures the cushions inflate and deflate completely in just 60 seconds. This is faster than with the average leg massagers. In addition, the TruGrade technology ensures a safe and accurate pressure distribution. Connect the RecoveryAir JetBoots Large to the Therabody app for a pre-set warming up and recovery program.
