Saucony Endorphin Speed 4 Sneaker - Fast, Light Training Shoe

In this review of the Saucony Endorphin Speed 4 Sneaker the bottom line is simple: this shoe is for runners who want a fast, light trainer that still offers comfortable cushioning for daily miles. The design leans race-ready while keeping enough support for repetitive training, and the single biggest reason to buy is how the combination of PWRRUN PB cushioning and a responsive plate creates a lively, efficient ride that helps sustain a quicker cadence without feeling harsh on the feet.

Key Features

• FAST & LIGHT: Built to feel noticeably lighter on the foot so runners can push pace during tempo runs and shorter races with less fatigue.
• PWRRUN PB cushioning: Delivers a plush yet responsive midsole that preserves energy return for consecutive miles and improved comfort.
• SPEEDROLL geometry: Encourages a smooth forward roll through the gait cycle to make transitions feel quicker and more efficient.
• SRS: Stability and structural support in targeted areas help maintain form without adding unnecessary weight.
• PLATE: A built-in plate enhances propulsion and creates a springy feel especially noticeable at faster paces.

Who It's For

The Endorphin Speed 4 is ideal for trained runners and fitness enthusiasts who want a versatile daily trainer that doubles as a tempo or short race shoe. It fits well for those who prize lightweight construction and energetic cushioning when doing regular speed work or race-specific sessions.

Runners who need a very precise fit or who prefer maximal, plush cushioning for long recovery runs may want to look elsewhere; some customers reported mixed experiences with fit, so anyone with unusual sizing needs should try them on to ensure the best fit.
