I'm planning on buying the walking boots as the shaft is slightly higher. But not so much for everyday use as for the holidays. When you really walk or hike longer distances. One reason they're so great is that you don't feel the stones. I usually walk the dogs on a natural path, and then you're happy if you don't feel every stone.
After 18 full marathons and several half ones, I recently had to quit running because of pain in the lower back and the legs. The medical diagnosis was Spinal Stenosis. But I never stopped moving. Thanks to the combination of kybun shoes and Pilates, I am able to make long walking-tours and hiking in the wonderful Finnish nature.
