I probably wouldn't recommend wrapping your feet unless you've specifically been instructed to do that by your doctor. Is your 160 mile walk going to be on uneven terrain, or on pavement? I'm wondering if maybe you need to wear supportive walking shoes instead of boots and that might fix the problem.
