Compression locked heels eliminate lift during steep inclines

Engineered for elite marathon racing, The Flash-1 delivers next-level propulsion with ultra-lightweight design and advanced carbon technology. Upgraded SPACE 2 midsole foam perfectly balances softness, comfort and resilience. It delivers more aggressive rebound feedback, creating an extraordinary ride for speed-focused runners. The midsole is embedded with a carbon plate that extends upward on both sides, delivering surging propulsion while maintaining torsional stability and lightweight integrity. A sculpted geometric midsole reduces excess weight while enhancing structural support. Featuring a featherweight see-through upper, it feels like being wrapped in socks.
