Wearing kyBoot feels like walking on air. I wear them while travelling and it makes walking long distances an ease. Best part was I wore the kyBoot during the entire Singapore F1 race. Being a volunteer marshal, I need to be alert, on our feet, standing and walking for 15 hours every day for the entire race weekend. Wearing the kyBoot made this experience very enjoyable as I felt much less fatigue.
It resulted in some sore muscles, because the position was unfamiliar. It was airy, but you get used to it and now I enjoy it a lot. I also feel the relief in my knees.
