Frequently Asked Questions

• What’s the difference between Saucony’s PWRRUN, PWRRUN PB, and PWRRUN HG foams, and which should I choose?

  PWRRUN is a durable EVA blend used in daily trainers like the Ride and Guide for balanced cushioning and longevity; PWRRUN PB is a much lighter, high-rebound foam found in performance trainers such as the Endorphin Speed and Tempus that delivers a bouncier, more responsive feel for faster workouts; PWRRUN HG is an ultra-light, very high energy-return foam used in premium racers like the Endorphin Elite 2 for maximum propulsion. Choose PWRRUN for everyday training and durability, PWRRUN PB when you want fast workouts and tempo runs with a lively ride, and PWRRUN HG when you prioritize top-end race performance.
• How does the Endorphin Speed compare to the Endorphin Pro for racing and training?

  The Endorphin Speed uses a full-length nylon plate with PWRRUN PB for a more flexible, versatile ride that’s ideal for fast workouts, tempo runs, and short-to-mid distance races you’ll also train in. The Endorphin Pro pairs a full-length carbon-fiber plate with highly reactive foam for a stiffer, race-focused platform that favors dedicated race-day speed on fast courses.
• Which Saucony models are best for daily training versus maximum-cushion recovery runs?

  For everyday mileage and mixed paces, the Ride and Guide (PWRRUN midsole; Guide adds guidance/support) offer a good balance of responsiveness and durability. For long recovery runs or maximum cushioning, the Triumph 22 and other max-cushion models use PWRRUN+ and broader width options to provide extra protection and a roomier fit.
• How should I approach sizing and fit with Saucony shoes given their FORMFIT and dynamic lasts?

  Saucony’s FORMFIT system and dynamic lasts use engineered mesh, contoured footbeds, and memory-foam collars to adapt to foot shape, but lasts differ between models and genders so fit can vary significantly across the lineup. If you have a high instep or wider foot, look for models offering broader widths (for example, Triumph 22) and follow each model’s specific size guidance rather than assuming identical fit across all Saucony shoes.
• What is SpeedRoll and how will it change the way a shoe feels when I run?

  SpeedRoll is Saucony’s rocker geometry with pronounced heel and toe angles designed to promote forward propulsion and smoother transitions through the gait cycle; paired with responsive foams like PWRRUN PB, it helps maintain speed with less perceived effort at threshold and faster paces. Expect quicker toe-off and a more energetic feel during tempo runs and races without needing major changes to your stride.
