Saucony Women's Endorphin Speed 3 - Fast, Smooth Daily Trainer

Our review of the Saucony Women's Endorphin Speed 3 finds it best suited to runners who want a versatile, responsive daily trainer that still performs on faster workouts. The single biggest reason to buy is the reimagined S-curve winged nylon plate, which centers and supports the foot for a lively, connected ride without feeling like a rigid racing shoe. The updated geometry and redesigned upper combine to deliver a smoother, springy experience whether logging long miles or pushing tempo efforts.

Key Features

• S-curve winged nylon plate: Centers and supports the foot to provide stability and a balanced, propulsive feel during daily training runs.
• Updated geometry: Delivers a smoother ride with more pop and spring, making transitions quicker and cadence feel more natural.
• Redesigned upper: Offers a comfortable fit from heel to toe that reduces hotspots and enhances lockdown for varied paces.
• Daily training focus: Built to bridge easy miles and faster workouts, giving runners versatility across different sessions.
• Responsive feel: The combination of plate and geometry provides tangible energy return helpful for tempo runs and brisk long runs.

Who It's For

The Endorphin Speed 3 is aimed at recreational and club runners who want one shoe that can handle steady weekly mileage and faster workouts without switching models. Runners seeking a lively but not extreme racing plate will appreciate the centered support and springy geometry for both short faster efforts and longer training days.

Those who prefer a very soft, maximal cushion or a pure carbon-raced shoe for marathon day should look elsewhere, since this model trades extreme cushioning and full carbon stiffness for a balanced, responsive daily trainer with a nylon plate.

Pros & Cons

Pros

• Strong midfoot support and centered propulsion from the S-curve winged nylon plate.
• Smoother ride and extra pop from the updated geometry, helpful during tempo work.
• Comfortable, redesigned upper that improves fit from heel to toe.

Cons

• Not a maximal-cushion shoe, so runners who want plush long-run softness may prefer a different model.
