The Endorphin Speed series is ideal for runners who want one shoe that can do it all: fast enough for racing, cushioned enough for regular training, and responsive enough to make speedwork feel effortless. The nylon plate through the midsole delivers a clear sense of propulsion without the harshness of a full carbon plate, making it more comfortable for everyday miles while still giving you race‑day snap when you need it.
SPEEDROLL technology helps you roll forward smoothly and maintain your rhythm over longer efforts, reducing the braking effect that can slow you down and tire your quads. With a generous stack of PWRRUN PB foam, the shoe protects your legs on higher‑mileage weeks while still feeling light and bouncy enough for fast finishes and progression runs.
A breathable, lightweight mesh upper keeps your foot secure and cool during hard efforts, with a precise fit that locks you in without feeling restrictive around the midfoot and heel. The updated outsole offers better grip and durability for longer wear, giving you confidence on wet roads, tight corners, and track sessions without wearing through too quickly. At around 230–240g, depending on size, Endorphin Speed feels noticeably lighter than a traditional cushioned trainer but substantial enough to handle regular training volume.
A full-length semi-rigid nylon plate between two layers of responsive PWRRUN foam, giving you a perfect balance of propulsion and cushioning with every stride.
