Full details

Featuring advanced PWRRUN PB cushioning and a specialized plate system, this shoe is perfect for tempo runs and daily training sessions; however, its specialized geometry may require a brief adjustment period for those transitioning from more traditional, lower-stack running shoes.

FAQs

Is the Endorphin Speed 5 suitable for racing?

Yes, it is highly capable for racing, particularly in distances from 5K up to a marathon for runners who prefer a snappy, cushioned feel.

How do I determine my size?

The Saucony Endorphin Speed 5 typically runs true to size, but we recommend selecting your standard UK athletic footwear size.

Can I use these for trail running?

These trainers are designed for roads and smooth surfaces; the outsole is not built for the traction required on loose or technical trails.

What is the primary difference in the new plate?

The redesigned plate in the Speed 5 focuses on providing a smoother transition and enhanced stability compared to previous iterations.

How long should the foam last?

The PWRRUN PB foam is durable, but as with any performance trainer, expect the responsiveness to begin fading after 300-500 miles of usage.

Troubleshooting

Feeling of instability during cornering

The shoe's stack height is designed for forward propulsion; practice taking corners with a slightly slower pace and more deliberate foot placement.

Upper material showing minor debris accumulation

Use a soft-bristled brush to gently remove dirt from the nylon fibers after your run to maintain breathability.

Pros and Cons

Pros

  • Highly responsive cushioning for fast-paced training
  • Lightweight construction reduces fatigue over long distances
  • Unique, aesthetic floral print and colorway design
  • Versatile performance for both tempo and daily miles

Cons

  • Specialized plate geometry may feel unstable to some users
  • The nylon upper is breathable but less water-resistant than heavier materials
  • Limited to specific design aesthetics due to the unique Kissaten branding

Setup, Compatibility & Care

To ensure the best experience, break in the shoes with shorter, low-intensity runs to allow your feet to adapt to the rocker-style geometry. Since these are performance trainers, they are best suited for road surfaces or smooth tracks. For care, avoid putting the trainers in a washing machine, as the heat and agitation can degrade the midsole bonding. Instead, spot clean the nylon upper with a mild detergent and a soft cloth, and allow the shoes to air dry away from direct heat sources to preserve the structural integrity of the PWRRUN PB foam.
