Saucony Women's Endorphin Speed 2 Running Shoe - Responsive Race Shoe

Our review finds the Saucony Women's Endorphin Speed 2 is a purpose-built lightweight trainer for runners who want a fast, efficient ride without sacrificing day-to-day comfort. Built around Saucony's SPEEDROLL Technology and a responsive PWRRUN PB midsole, this shoe is best for tempo runs, speed sessions and race day when momentum and energy return matter most. The updated heel shape and slip laces aim to hold the foot securely, while recycled upper materials and a vegan construction reduce environmental impact compared with heavier racing shoes.

Key Features

• SPEEDROLL Technology: Propels the runner forward with a feeling of continuous momentum so efforts feel more efficient and less fatiguing.
• PWRRUN PB Cushioning: Ultralight and springy cushioning delivers versatile energy return for both fast workouts and race paces.
• Flexible Nylon Plate: Provides a stiff forefoot that enhances propulsion without the harsh snap found in some carbon plates.
• Superior Fit: Fine-tuned heel shape and updated slip laces keep the heel locked down and reduce slippage mile after mile.
• Eco-conscious Upper: A lighter footprint with recycled materials and a vegan design lowers environmental impact while keeping weight down.

Who It's For

The Endorphin Speed 2 is ideal for recreational and competitive women runners who prioritize speed work and races but still want a shoe that can handle repeated tempo sessions. It suits athletes who appreciate a lively, responsive midsole and a forward-propelling feel for short to mid-distance efforts.

Runners who need maximum cushioning for long slow runs, heavy stability features for overpronation, or a noticeably wider toe box should look elsewhere. This shoe favors a performance fit and a firmer forefoot designed to translate effort into propulsion.

Pros & Cons
