Studies have shown that 70% of all women and 40% of all men have health issues such as blood clots, varicose veins and pressure on the Achilles tendon due to pooling of fluids in the lower limbs —the result of prolonged, inactive sitting. The foot machine, with its ball-bearing, roller design encourages gentle rocking of the feet in the same way a rocking chair encourages movement. This rocking motion uses most of the lower leg muscles and increases healthful circulation. The foot machine also performs as a standard foot rest, providing support for the legs and relieving pressure on the lower back.
