My BOB includes a pair of the sneaker-type hiking boots in a head -to-toe change of layered clothing from the skin out. I reasoned that I could not predict how I would be dressed when I needed to bug out.

Edit: [Forgot] I also include a pair of low-cut, lightweight water shoes for my in camp, middle of the night, and change of pace needs. They take up little space and are perfect for storing an extra pair of socks.
