On one side is the Rocket X 3, which is the safer and more stable bet for marathon runners looking for something more accessible. On the other hand, for those looking for a more lively experience, there is now the Cielo X1 3.0. Unveiled Thursday, the newest Cielo X1 focuses on improving weight and control without sacrificing the progressive, bouncy sensation of the popular 2.0 edition. A men’s size 10 comes in at 7.5 ounces, which is 0.6 ounces lighter than the Cielo X1 2.0 and 0.5 ounces lighter than the Rocket X 3.
