I'm happy when I can change my shoes. I had to strut around in high heels on the gravel, and on top of that I had stones in my shoes. I'm glad I can put my kyBoot shoes back on.
The basis is in the sole of the shoes. They give you great exercise. And I feel like a child bouncing on a mattress, that's probably the best way to describe the feeling. After a long day at work spent Standing and walking, you can feel the difference.
