All technological advancement in running shoes over the last 50 year has increased energy return from the shoe. No midsoles to midsoles. Cut EVA to compression molded EVA. Different types of of compounds within the EVA. Air bags. Track spikes have gone from plastic spike plates to p-back plates to carbon plates. All of these developments have increased energy return and made the shoe and those wearing them faster. Vapor fly 4% are just a extension of this evolution of shoe technology. But the shoe is still a "passive"- energy out does not equal energy in. At what point do you stop technology advancement? How far back do you go?
