Endorphin Speed 4 Women's Running Shoe - Responsive Daily Pace

In this review the Endorphin Speed 4 is presented as a daily trainer for runners who want a lively, efficient ride without sacrificing comfort. The single biggest reason to buy is the shoe's proprietary combination of a smooth SPEEDROLL platform with ultra-responsive PWRRUN PB foam, which creates an effortless forward motion that feels fast even on regular training runs. Fit and finish are purposeful: an improved zonal mesh and integrated tongue aim to keep the foot secure while a new SRS sockliner adds a bouncy, cushioned feel for miles.

Key Features

• SPEEDROLL technology: Promotes an efficient, rolling gait that helps sustain faster paces with less perceived effort.
• PWRRUN PB foam: Superfoam cushioning that snaps back for energetic toe-off and long-run comfort.
• Zonal engineered mesh: Provides targeted breathability and a connected, secure fit across the midfoot.
• SRS Super Responsive Sockliner: Adds immediate underfoot bounce that enhances responsiveness on every stride.
• Re-engineered plate: Vertical reinforcement increases torsional rigidity while preserving forefoot flexibility for smoother transitions.

Who It's For

The Endorphin Speed 4 is best for road runners who train regularly and want a shoe that feels fast yet comfortable for tempo runs, intervals, and longer daily miles. It will appeal to runners who value a springy, energetic ride and who appreciate modern, engineered uppers that lock the foot in place.

Runners who need a very wide toe box or those looking for maximum plushness for long recovery runs may prefer a different model; some users report the fit runs narrow, so people with consistently wide feet should try them on first.

Pros & Cons

Pros

• Effortless forward motion from the SPEEDROLL platform that aids faster paces.
• Secure, connected fit from zonal engineered mesh and the integrated tongue.

Cons

• Some runners may find the fit too narrow, so sizing up or trying on is recommended.
