Saucony Endorphin Speed 5 Women Running Shoes White S11007-97

The Saucony Endorphin Speed 5 (Style Code: S11007-97) in “White” is the latest evolution of the shoe that defined the “super trainer” category. Released in 2025, the Speed 5 is designed to be a versatile powerhouse—comfortable enough for daily miles but snappy enough for race day.

The “White” colorway (often accented with “Mutant” neon or “Navy” details depending on the specific retail release) offers a clean, high-performance look.

Core Performance Features

• PWRRUN PB Midsole: The core remains Saucony’s signature PEBA-based superfoam. In the version 5, the foam has been “tuned” to feel slightly softer and more forgiving than the version 4, while maintaining its famous bounce.

• Redesigned Nylon Plate: The shoe features a semi-rigid nylon plate. In this update, Saucony moved to a single medial wing design (versus the dual wings on the Speed 4). This change allows for better midfoot flexibility and a more natural foot strike while still providing that “pop” at toe-off.

• SPEEDROLL Technology: The aggressive rocker geometry is designed to create a feeling of continuous forward momentum, making your turnover feel effortless even as you fatigue.

• Lightweight Construction: Weighing in at approximately 7.2 oz (204g), it remains one of the lightest trainers in its class, ensuring it never feels bottom-heavy.

Design & Fit Updates

• Engineered Hexagon Mesh: The new upper is a single-layer mesh that is significantly more breathable than previous versions. It is designed to “disappear” on the foot while providing a secure midfoot lockdown.

• Spacious Toe Box: Early feedback suggests the Speed 5 has a slightly more accommodating forefoot than the Speed 4, making it a better fit for runners who felt previous versions were too narrow.

  Enhanced Outsole: It utilizes XT-900 carbon rubber with a new longitudinal groove for smoother transitions and increased rubber coverage in the heel for better durability for heel strikers.

• SRS (Super Responsive Sockliner): A premium supercritical foam insole that provides an immediate, plush step-in feel.

Ideal For:

• Speed Work & Tempos: Its natural habitat. It excels when you want to run fast without the harshness of a carbon-plated racing flat.

• The “One-Shoe” Quiver: If you only want one pair of shoes for training and racing, this is the top contender.

• Marathon Training: Excellent for those long runs that include pace work or “marathon effort” segments.
