It really is. I once broke my foot running up some stairs. It was an emergency and as I was running I caught the edge of one step with just two toes(I did have shoes on) the ball of foot missed the stairs completely. Instead of slowing down or trying again I just pushed hard throwing my weight forward. Find out later that I had a radial fracture of my second metatarsal. The crazy thing is I spent the next few hours walking on a broken foot and didn’t feel it at all.
I did feel it the next day though. Fuck that hurt .
