"Women's Saucony® Endorphin Speed 4: The Women's Saucony Endorphin Speed 4 is a neutral road running shoe built for runners who want to move fast without sacrificing cushioning. With max cushion underfoot and SPEEDROLL technology that promotes a natural forward roll through each stride, this shoe has an energetic, propulsive feel that makes it easy to pick up the pace - whether you're logging daily training miles or pushing through a road race. At 7.2 ounces and an 8mm heel-to-toe drop, it runs light and lively without feeling stripped down.The PWRRUN PB superfoam midsole snaps back quickly underfoot, so the cushioning stays responsive rather than feeling soft and slow. A re-engineered winged nylon plate works with the foam to keep your turnover smooth and efficient. The zonal mesh upper moves air through the shoe as you run, keeping things cool during harder efforts, and the SRS sock liner adds a comfortable, close-to-foot feel from the first step. The lattice-designed outsole keeps the shoe light while providing reliable traction on road surfaces.Why Our Fit Experts Love This Shoe""I put these on for a tempo run and immediately noticed how quickly the foam rebounds - it doesn't feel like you're sinking in, it feels like the shoe is working with you. The SPEEDROLL geometry really does make a difference when you're trying to hold a faster pace for a longer stretch."" - Sabrina, Road Runner Sports Fit Expert, San Diego, CAWho It's Best ForIf you're a neutral runner looking for a fast-feeling, well-cushioned road running shoe that handles both daily training and race day, the Endorphin Speed 4 is worth a serious look. It suits runners who want responsive cushioning and a forward-moving ride without going to a minimal setup - especially those training for longer distances like half marathons or marathons who still want a shoe that feels quick. If you size up in running shoes, note that this one fits best going up a half size. VIP Family members can take the Endorphin Speed 4 for a 90-Day test drive with our Perfect Fit Guarantee."
