The Streakfly 2 helps you outpace your rivals on race day. This sprinter's shoe has a carbon-fiber Flyplate that works with an ultra-responsive ZoomX Foam midsole and the minimalist upper you liked on the original. From 1 to 10 km, they take your distances to the next level.'
What they're for: Racing short, fast distances on pavement, from 1 to 10 km. They weigh about 145 g (men's US size 10) and have a 4 mm heel-to-toe drop.
What's new: A full-length carbon-fiber Flyplate that gives a sense of propulsion.
