Product Information

Full details

The Saucony Endorphin Speed 5 is a high-performance trainer designed for neutral runners who prioritize speed and efficiency during track workouts or race-day efforts. Featuring a re-engineered plate and premium foam, it offers a snappy, smooth ride that encourages faster paces; however, runners seeking a traditional, ground-feel shoe may find the stack height and aggressive rocker geometry to be an adjustment.

FAQs

Is the Endorphin Speed 5 suitable for long-distance marathon training?

Yes, it is excellent for marathon training, particularly for tempo runs and long efforts where you need efficiency and reduced leg fatigue.

Does this shoe feature a carbon plate?

The Endorphin Speed 5 utilizes a specifically designed plate for responsiveness and stability, providing a snappy ride that differs from rigid carbon-plated racing shoes.

How should I clean my Saucony trainers?

Use a soft brush and mild soap to remove dirt. Hand wash only and air dry away from direct sunlight or heat.

Can I replace the insoles?

Yes, the insoles are removable and can be swapped for custom orthotics if necessary.

Are these shoes true to size?

Yes, the Endorphin Speed 5 fits true to standard adult sizing, though we recommend checking the size guide to match your specific UK size.

Troubleshooting

Heel slippage while running

Try using the runner's loop (heel lock) lacing technique to secure the ankle collar more firmly.

Feeling of instability at slower paces

The shoe is engineered for faster turnover; ensure you are landing mid-foot and maintaining a higher cadence to activate the plate's rocker geometry.

Pros and Cons

Pros

  • Excellent energy return from the PWRRUN PB foam
  • Snappy and responsive ride quality
  • Lightweight construction suitable for race day
  • Breathable upper for comfort during intense sessions

Cons

  • Aggressive rocker geometry may feel unstable for some users
  • Higher stack height may limit ground feel
  • Specifically tuned for speed, not ideal for slow recovery jogs

Setup, Compatibility & Care

To ensure the longevity of your Endorphin Speed 5 trainers, avoid using them in muddy or extreme terrain that could compromise the foam integrity. If the shoes get wet, remove the insoles and stuff the interiors with paper towels to draw out moisture; never place them near a heater, as direct heat can warp the cushioning foam. When fitting, ensure you have roughly a thumb's width of space at the front of the shoe to allow for natural foot swelling during longer, faster runs. Regularly inspect the outsole for excessive wear if you frequently use them on abrasive track surfaces.
