FAQs

What type of runner is the Saucony Endorphin Speed 5 designed for?

The Endorphin Speed 5 is ideal for neutral runners seeking a versatile shoe for various paces. It's excellent for race days, fast training sessions (tempo runs, intervals), and can also be used for spirited everyday runs.

Is the Endorphin Speed 5 suitable for daily training?

Yes, while it excels in speed-oriented sessions, its balanced cushioning and comfortable upper make it suitable for daily training. It offers a more energetic ride than a dedicated plush daily trainer.

What is PWRRUN PB foam?

PWRRUN PB is Saucony's premium, PEBA-based midsole foam. It's known for being highly responsive, lightweight, and providing significant energy return, contributing to the shoe's propulsive feel.

Does this shoe have a carbon plate?

No, the Endorphin Speed 5 features a semi-rigid, winged nylon plate. This provides a snappy, propulsive feel and added stability, offering a slightly more forgiving ride than a full carbon plate while still being very fast.

What is the heel drop and stack height of the Endorphin Speed 5?

The shoe has an 8mm heel offset (drop) with a stack height of 36mm in the heel and 28mm in the forefoot. This configuration is designed for a balanced and efficient ride.

How should I clean my Endorphin Speed 5 shoes?

It's best to hand wash your shoes with mild soap and cold water. Gently scrub away dirt, then rinse thoroughly. Allow them to air dry completely, away from direct heat or sunlight.

Does the outsole provide good grip on various surfaces?

Yes, the Endorphin Speed 5 is equipped with PWRTRAC rubber on the outsole, which is designed to provide reliable traction on a variety of surfaces, including asphalt, track, and even some light park paths.

Troubleshooting

Shoe feels too firm or not as responsive as expected.

Allow for a brief break-in period of a few runs. The PWRRUN PB foam and nylon plate will adapt to your foot and running style. Ensure your lacing isn't overly tight, restricting natural foot flexion.

Slipping sensation on wet or slightly challenging surfaces.

While the PWRTRAC outsole offers good grip, no shoe is entirely slip-proof. Ensure the outsole is clean of debris. Adjust your stride on slick surfaces to increase ground contact time and reduce impact forces.

Upper feels either too tight or too loose during runs.

Experiment with different lacing techniques. If too tight, try skip-lacing certain eyelets. If too loose, ensure you're using all eyelets and consider a runner's knot for a more secure heel lock. Verify you have the correct shoe size for optimal fit.

Developing hotspots or minor foot discomfort after extended runs.

Review your sock choice; moisture-wicking running socks are essential. Gradually increase your mileage in new shoes to allow your feet to adapt. If discomfort persists, ensure the shoe size is appropriate and consider consulting a running specialist for gait analysis.

Unusual wear patterns on the outsole.

This can indicate aspects of your running gait. While the optimized outsole is durable, excessive wear in specific spots might suggest a need for gait analysis or a review of your running form. Ensure you're rotating your running shoes to extend their overall lifespan.

Pros and Cons

Pros

  • Excellent propulsion and speed due to the nylon plate and Speedroll geometry.
  • Comfortable and responsive cushioning provided by PWRRUN PB foam.
  • Highly versatile, performing well for races, tempo runs, and everyday training.
  • Improved outsole durability, especially in the heel.
  • Breathable and lightweight upper ensures comfort during long efforts.
  • Reliable grip on diverse surfaces with PWRTRAC rubber.

Cons

  • The semi-rigid plate may feel firmer than dedicated plush daily trainers.
  • While stable for a tempo shoe, it may not provide maximum support for runners needing high pronation control.
  • Optimized for speed, it might not be the ideal choice for purely slow, recovery runs where maximum softness is desired.
  • Lighter construction might imply a slightly shorter lifespan compared to more robust, heavier trainers.

Setup & Compatibility

To optimize your experience with the Endorphin Speed 5, ensure a proper fit. Lace the shoes snugly but not too tightly, utilizing all eyelets for a secure, locked-down feel, especially before faster efforts. The shoe is designed for neutral runners and is highly versatile, suitable for a range of distances from 5k to marathons. It performs best on road surfaces, tracks, and well-maintained park trails.

Care Instructions

Proper care will extend the life of your Endorphin Speed 5:

  1. Cleaning: Remove any loose dirt with a soft brush (e.g., old toothbrush) after runs. For deeper cleaning, hand wash with mild soap and cold water. Avoid harsh detergents or hot water.
  2. Drying: Air dry your shoes away from direct sunlight or heat sources. Remove insoles and stuff the shoes with newspaper to absorb moisture and maintain shape.
  3. Storage: Store your shoes in a cool, dry place. Avoid leaving them in direct sunlight or extreme temperatures.
  4. Avoid Machine Washing/Drying: Machine washing can damage the materials and adhesives, while machine drying can cause shrinkage and material degradation.
