A DURABLE TRAINER, MADE TO BREAK RECORDS. While these speedsters could easily pass the test on race day, they double as your go-to shoe for your training routine. The supportive fit and soft cushioning work together to make them comfortable enough to withstand those double-digit mileage days, and light enough to help quicken your tempo when the time is right.

Runner-Informed Traction Using data from hundreds of runners, traction is placed where your foot needs the most grip on multiple surfaces. Fast Fit A translucent Flyknit upper provides breathability in areas where your foot heats up most. It uses strong, stretchy yarns to create a lightweight yet supportive feel with every mile. Asymmetrical lacing helps keep your foot secure and in place. Semi-adhesive removal sockliner allows for easy replacement.
