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've been wearing these shoes for a year and my problems have all gone: no lumbago, nothing. It's just vanished.
As your feet have to move about a lot more, somehow the calluses just go away. I don't have cracked skin any more in the winter. I always had really deep cracks in the heel and my entire foot, really. I don't have that at all any more. I do still have to rub cream in, as they are still quite dry, but it's not as bad as how it used to be.
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.
