Margrith Sibold from Switzerland

I had an operation on my inner knee joint in January 2014. I realised afterwards that walking in this shoe is extremely good for me. I no longer felt the impact of the ground. I felt like walking in the kybun shoe was very beneficial for my health after the operation.

My posture has improved. I walk nice and upright and don't have any pain in my upper body any more, especially my shoulders. It feels like your stomach, legs and bottom are being toned. It's a great physical feeling!

As you're walking, it's springy. You're not simply walking on the hard ground. I don't know what it is, but in any case I don't have any back pain any more. It's striking. I used to have a lot of back pain if I spent a long time standing.
