Revs® are defined by our unique Reflexology Massage Footbed. Revs® have a soft, comfortable yet durable sole constructed to ensure the position, width and height of each and every massage nodule sits and hits the right spot on your feet, maximising the effectiveness of the massage on the reflexes and nerve points, just as a reflexologist would during a treatment. This means with each step, or even when standing, you are massaging and stimulating your organs, and muscles and parts of your body. You might find parts of your feet are sensitive if there is an imbalance or congestion in the corresponding part of your body, for example, if you have a sore shoulder you might find the sole of your foot sore just under the pinky toes; or if you suffer from constipation, you might find your colon reflex is a little tender until the nodules gently decongest the blockage there. Here is more information on how Reflexology and Revs® can assist in improving your health and well-being. You can also view the Reflexology Chart to understand which parts of the feet map to the body. This is really helpful for understanding your body and how Revs® Reflexology Massage Flip Flops work.
