These cutting-edge trainers can handle longer distances and larger-frame runners, thanks to nitrogen-infused N2 cushioning technology that's low to the ground. Stabilicore platform gives you enhanced stability, providing you with both a midfoot strike as well as a more traditional heel strike. Lightweight and flexible T-beam shanks deliver optimum stability and arch support through a unique center-beam design. Abzorb® compression technology pads your feet to ensure even, shock-free strides. Midsoles are made of Acteva™ Lite premium material that's 24% lighter than standard foam, and still performs with optimal resistance to compression. The no-sew uppers have welded seams for a supportive and intensely comfortable fit with minimal rubbing, and Airmesh™ material provides superior airflow. N-durance® blown-rubber outsoles add to the smooth ride, and reflective detailing enhances your visibility. This dynamic package gives you responsive, durable and sustainable shoes for a plush and enjoyable experience with premium shock absorption. Made in USA with imported parts. Men's sizes: 8-16 B width; 7-16 D, EE and 4E widths. Half sizes to 13. Colors: Formula 1, White/Black.
