This is interesting. Apparently, when a person is running, they collide with the ground with a force about three to four times their body weight with each stride. That is a lot of responsibility, and weight, to be putting on your poor old toes. Proper footwear aside, it makes one wonder how so many runners survive without doing some very costly damage to themselves. There is a former Olympic gold-medalist runner living in the same retirement building as my grandmother. He's a really nice old guy. I've got a copy of his book around somewhere that I haven't read yet.
