Endorphin Speed 6 Women's

Features Saucony’s PWRRUN PBX superfoam is new for this generation, and it's the reason the Endorphin Speed 6 sits 2 mm taller underfoot without weighing more. Most shoes that add stack also add grams, and this one adds softness and rebound while staying at 6.9 oz. The result is a supertrainer that makes your tempo session, and the easy day after it, equally as fun. A redesigned nylon plate runs through the midsole and drives your transitions. The nylon flexes in a way carbon doesn't, so you get snappy propulsion through toe-off without the rigid, all-or-nothing feel of a race shoe — which is what makes the Speed 6 so versatile across a range of paces. The lightweight mesh upper holds your foot in place when you shift gears and keeps you comfortable throughout your run. Details: Upper: Breathable lightweight mesh keeps your foot locked down when you pick up the pace. The construction stays minimal to hold weight down without giving up security through turns and faster efforts. Midsole: PWRRUN PBX is a next-generation superfoam that delivers more cushioning and better efficiency at a lower weight than the foam it replaces, with 2 mm more of it underfoot. A newly designed nylon plate sits inside the midsole and adds propulsion through smoother, faster transitions. An SRS sockliner tops the platform for step-in comfort. Outsole: Strategic rubber coverage in the heel and forefoot handles the traction demands of road miles at tempo pace. What's New PWRRUN PBX superfoam replaces the previous midsole foam and brings more cushioning and more efficiency at a lower weight, with 2 mm of additional stack underfoot. The nylon plate has been redesigned for stronger propulsion and smoother transitions through your gait cycle. The upper has been rebuilt in lightweight breathable mesh for a more secure hold when you pick up the pace. Together those updates make the Speed 6 more cushioned and more responsive at once, beyond what earlier versions offered. Who It's Best For Runners who want one shoe for tempo work, intervals and everyday training, especially anyone who finds a full carbon racer too aggressive for daily use. It's also a strong fit for runners building toward a goal race who want plate-driven propulsion in a shoe they can log real volume in. Why You'll Love It You get the pop of a plated shoe with enough cushioning to keep using it the next day. When one pair covers your workouts and your easy miles, your rotation gets a lot simpler.
