At first I found it quite hard going. It's unusual; a different kind of “standing”. I concentrated more on my feet than on what I was singing.

"The kyBoot means you can walk actively and healthily even on hard surfaces. The soft, unstable sole is kind on your joints, exercises your muscles, improves your balance and stimulates receptors in your feet. From a medical perspective I thus specially recommend the kyBoot to patients with poor posture or knee problems."
