 Whether you're pushing the pace on tempo runs or cruising through longer distances, the Speed 4 delivers a smooth, efficient ride that feels fast but controlled.

At the heart of the shoe is PWRRUN PB cushioning, a high-performance foam that strikes the perfect balance between softness and responsiveness. It provides noticeable energy return while still offering enough cushioning to stay comfortable on longer runs—making it one of the most versatile midsoles in the performance category. Paired with a re-engineered winged nylon plate, the Speed 4 adds structure and snap without the stiffness of a carbon-plated racer, giving you a more forgiving and adaptable ride for everyday training.

The updated design also brings improved traction and durability underfoot, helping you feel confident across different surfaces and conditions. Up top, the lightweight engineered mesh upper offers breathable comfort with a secure, dialed-in fit that works for a variety of foot shapes. The result is a shoe that feels equally at home during speed workouts, long runs, and even race day—making it a true “super trainer” for runners who want performance without compromise.

If you’re looking for a do-it-all running shoe that blends speed, cushioning, and versatility, the Women’s Endorphin Speed 4 continues to stand out as one of the best options in its class.
