The original Endorphin Speed is a lightweight road shoe for speed training and race day. Flexible PWRRUN PB works with SPEEDROLL and a semi-rigid nylon plate to deliver propulsion with a more forgiving feel than the carbon-plated Pro. At 221g with an 8mm drop and 35.5/27.5mm stack, it suits tempo sessions, longer fast runs and racing. ABC-MART's Japan release launched it on August 1, 2020.
