Fit for the world's fastest, the Maxfly 2 is back in the starting blocks. Designed for the 100 meters to 400 meters (hurdle events too), it combines an ultra-aggressive feel with the responsiveness of an Air Zoom unit to propel the speediest sprinters on the planet. We updated the base and upper from the previous iteration to help optimize the Air Zoom unit's speed. You also get improved stability and control on both straightaways and turns as you hightail it to the tape.
