Athlete-tested innovation for next-level racing speed, from 400m to 1500m. The meticulously engineered inverted spike plate helps transfer your force on the track into maximized energy return for propulsive turnover. Our unique plate design features a top-loaded carbon fiber plate and a bottom-loaded Pebax spike plate, which optimize bending stiffness and help give back the energy you transfer with each step, so you can get onto your toes for that final kick or mid-race surge. Our 100% TPU woven upper is anatomically designed to create the ultimate locked-in fit for any speed on race day. 100% PEBA DNA GOLD cushioning is the lightest, softest, and highest energy return foam Brooks® has ever made. This nitrogen-infused foam, paired with the propulsive inverted spike plates, helps optimize torsional rigidity to push your speed limits. Compared to DNA FLASH v2, DNA GOLD is 11% lighter, 14% greater energy return, and 25% more flexible.
