Sir Issac Newton didn’t really consider the role of energy in this theory of gravity, but he’d likely still appreciate that Newton Running Shoes is inspired by his research. Understanding all of Newton’s (the brilliant man) concepts can be difficult for novices, but so can running with a pair of Newton shoes. The Newton Energy NR Guidance Trainer is designed to facilitate a seamless transition from conventional running shoes to the Newton way. These shoes will be ready to hit the road later this month.
