Adidas just revealed the new Switch FWD running shoes, which are said to convert gravity into forward motion. The new shoes are said to be the expansion of the FWD line, consisting of the Adidas 4DFWD and the second iteration of the shoes, the aptly-named Adidas 4DFWD 2.
The main difference between those and the Switch FWD is the midsole material. Constructed using 'cutting-edge design processes', the new EVA compound midsole features 'intricately designed' voids that collapse and spring forward, converting gravity into forward motion.
