Corporate Level! Nike Air Zoom Alphafly Next% 4, the new marathon ultra-running

Corporate Level! Nike Air Zoom Alphafly Next% 4, the new marathon ultra-running shoe, is the lightest and most tested Nk Alphafly ever. It has been tested and verified by elite marathon athletes and is equipped with Air Zoom air cushion, which is designed to help runners achieve breakthroughs and achieve better results. During the development process, Alphafly 3 helped Nike athlete Kelvin Kiptum to break the marathon world record with a time of 0:35. The dynamic design of Alphafly has not changed. The Air Zoom air cushion unit, Flyplate carbon fiber plate and Zoomx foam have been slightly adjusted to optimize and improve the help for athletes. Major updates include one-piece soles that provide a smooth and stable "heel to toe" transition; wider full-length Flyplate carbon fiber plate provides stable thrust. New Fast Shot outsole ensures excellent traction and grip. New Atomknit 3.0 upper provides greater control, breathability and midfoot support.
