I love winning an argument. For years I have heard the 'better half' complain about his low back pain and for years I have watched him walk lopsided like Amitabh Bacchan!! His feet dropped their arches and became flat! After repeatedly asking him to exercise and after repeatedly being ignored I discovered Vivobarefoot! They makes shoes to allow the natural movement of feet. Since feet are the only connection to the ground, they feedback to the rest of the body on how to stand and move. So, I saved up some money to invest in these shoes for his office. For weeks I haven't heard him complain about his back and he had been walking straight. However, yesterday he decided to wear his horrible Doc Martin type boots and walked for 20 mins. He came home complaining of back pain and headache!! Now he has sworn not to wear anything but Vivobarefoot again!! I WIN!!
