Magic sneakers

I finally found a pair of sneakers that fit my 14w foot, and they are magical. The last 7 miles, I have been trying to keep up with them, they are so fast. Going downhill, they are going so fast I am nearly tripping. It has crossed my mind that, its possible that having worn 20lb boots for the last month of walking, that by wearing these lightweight sneakers; I am just experiencing a lower gravity effect. But I choose the magical sneaker theory. Still miles to go, and walking on clouds.
