Back when I had a job, one of my PCs went sick after walking though his house barefoot, catching it on some furniture and almost severing his little toe. Would've put Hannibal Lecter off his dinner.
I go barefoot indoors in summer.
One day I took a running jump at the stairs in Stow on the Wold YHA, and stubbed my toe on a riser. That made my eyes water, and I don't know how I didn't break a toe, but it wasn't any bother on the bike the following day.
I stubbed my toes on a doorstep that protrudes out into the pavement on a training walk doing about 6mph, and one of my toes has always struck me as a bit misshapen since then.
