I was always a barefoot person outdoors. Always had dirty feet. Always loved the feel of grass & dirt around my toes.
UNTIL I GOT CHICKENS!!
Dirt & mud may be fine between my toes, but chicken poop is not. Plus, I'd rather inside the house be the one place that chicken-poop free. So beside the backdoor is always at least 2 pairs of old slip on shoes that I wear religiously. One pair is flip-flops, the other is a pair of old tennis shoes with the backs cut off.
It's amazing how clean my feet are now.
