I always wear slip-on type sandal shoes around the place - UNLESS I am handling in a horse who is naughty, new, or spooky. Even if it's just to move them to a different pasture, I'll put my boots on.

Feeding, haying, bringing up the ol' dead-broke, never-gonna-move-faster-than-you-make-him horse? Slip on sandals.

knock on wood, no foot injuries yet.
