This is mainly caused by long working hours with long periods of standing, heavy lifting and putting strain on one side of the body.
The kybun shoes promote well-being in the workplace. The walk-on-air sole of the kybun shoe provides optimal shock absorption and noticeably reduces the stress on the body. This allows you to float through your work day on the soft, springy air cushion sole.
I love wearing my kyBoot shoes, so I wear them almost daily. I always have them on at work. In my spare time I sometimes wear the sandals.
I used to put more weight on my right foot, because it's longer. So I always stood on that one. And then it simply wasn't balanced any more, and with these shoes it somehow levels itself out, and I was standing much straighter. Even when sitting I notice that now, already, after a year – it takes a while, it's not from one day to the next – that I am simply sitting much straighter and everything's different. My whole posture is different. All of it.
At first I often felt tired and my muscles ached. One reason was no doubt that I wore the shoes all day. I'd recommend that older People should start out more slowly. A young person can wear the shoes all day without any trouble. The aching muscles are nothing compared to the pain I used to have.
