In the northwest, temperatures rarely get above 60º. That means it's time to hibernate my bare soles, and break out my dress shoes (and eventually dress leather winter boots). One thing worries me, though. I don't want to lose my progress. I worked hard toughening my soles, and strengthening my (flat, weak) arches. With barefoot not even an option indoors (much too cold), how do I maintain the toughness of my soles and not let my arches weaken? I will have a few occasions where I can remain barefoot besides when I'm asleep, but those occasions will be few and spread.
