The Energy 2.0 provides a lively, performance-oriented ride. With only a 10mm difference between heel and forefoot (compared to the traditional 12mm), the Energy 2.0 is ideal for midfoot stikers and uptempo running. The upper has a bit of stretch and hugs the foot. With so much geared toward high performance, the shoe is a big surprise as it delivers everyday training comfort for neutral runners.
