My guy has stepped on my foot once in the 3 years I've had him.
He's a heavy guy, probably around 1600lbs. We were at a show, I was letting him graze after his last class of the day. The grassy area was in view of one of the arenas, so I was off in lala land watching the other horses warm up. He took a step forward, and managed to land on the outside edge of my right foot. I got a nasty bruise, and to this day ( over 2 years later) my skin is still red & blotchy in that area only. Doesn't hurt though.
