One of my colleagues is into feet. Like really into feet. She's so passionate that she's a Certified Healthy Foot Practitioner. I've greatly benefitted from her interest and knowledge. A few years ago, I was dealing with terrible, unexplained low back pain. Christina started talking to me about my feet...how much time I spent barefoot (or in my case, didn't) and what kinds of shoes that I wore. She helped me learn about minimalist shoes and zero-incline soles. She talked about how our feet are our foundation for our entire bodies' alignment. As I began to put Christina's recommendations into practice, a lot of my pain diminished. I spend a lot of my time barefoot. When I wear shoes, I almost always wear shoes that Christina would approve of. Every now and then, I pull on my cowboy boots or slip on a pair of heels. And I usually feel it in my back the next day.
