Going barefoot is healthy, comfortable, legal, generally safe and provides additional sensation and awareness of the world around us.
Our society wrongly believes that shoes are a necessary part of our daily lives. Actually, they provide a breeding ground for bacteria and weaken and misshape our feet. They can cause injury from our ankles up through our spines. Even flip flops alter our natural walking gait and collect bacteria.
All that said, footwear still has its place sometimes. Alternative shoes such as "minimalist" footwear are available to keep feet flexible and strong while offering some protection.
I encourage you to take one "step" out of your comfort zone by going barefoot someplace/sometime that you normally wouldn't. Rediscover and enjoy the amazing feet that the good Lord gave you!
